The present disclosure generally relates to anti-inflammation method for COVID-19 infected patients, and particularly, to a method for suppression of clonal expansion of highly activated and proliferative lymphocytes in COVID-19 infected patients and a consequent reduction in cytokines released by lymphocytes utilizing application of an alternating electric field (AEF) to a part of a patient's body infected with COVID-19 (e.g., lung tissue) with highly activated and proliferative lymphocytes therein.
More than 200 million infections with at least 4 million deaths worldwide is just a small part of the consequences that a 100 nm coronavirus has imposed on the world community since its emergence in 2019. After infection and commencement of the immunological phase of COVID-19 disease, many clinical manifestations may arise, but acute respiratory distress syndrome (ARDS) is one of the most lethal features of the COVID-19. Numerous pieces of evidence suggest that severity of COVID-19 infection and ARDS is highly correlated with the proinflammatory cytokine levels in bloodstream and an intensity of immune cell hyperactivation caused by the COVID-19 virus.
Out-of-control secretion of cytokine proteins with subsequent hyper-activation of immune system causes severe systemic damage to tissues and organs throughout an infected body, such as pulmonary dysfunction and renal failure. To prevent exacerbation and progression of coronavirus disease in such patients, a broad range of immunosuppressor drugs such as corticosteroids, JAK inhibitors, etc., are used as a general treatment. For instance, dexamethasone therapy has shown promising results in reducing severity of COVID-19 infection, suppressing cytokine storm, and consequent hyperinflammation phase of coronavirus disease. One major effect of the immunosuppressor drugs such as dexamethasone is their antiproliferative effect. In fact, dexamethasone impairs proliferation of lymphocytes such as T cells during their clonal expansion. Although many benefits are associated with administration of dexamethasone for suppression of severe inflammations, numerous negative serious side effects such as increased risk of sepsis, calcium metabolism, kidney disorders, etc., are also inevitable.
Hence, there is a need for a simple, fast, and cost-effective method, system, and associated apparatus for suppressing cytokine storm in patients who are infected with an inflammatory disease or a hyperactivation of immune system, such as COVID-19 patients. There is even a need for preventing cytokine storm in patients with hyperactivated immune system at early stage of their disease, specifically, in COVID-19 patients. There is also a need for method, system, and associated apparatus for preventing or suppressing cytokine storm in patients without causing any significant side effects.

The following detailed description is presented to enable a person skilled in the art to make and use the methods and devices disclosed in exemplary embodiments of the present disclosure. For purposes of explanation, specific nomenclature is set forth to provide a thorough understanding of the present disclosure. However, it will be apparent to one skilled in the art that these specific details are not required to practice the disclosed exemplary embodiments. Descriptions of specific exemplary embodiments are provided only as representative examples. Various modifications to the exemplary implementations will be readily apparent to one skilled in the art, and the general principles defined herein may be applied to other implementations and applications without departing from the scope of the present disclosure. The present disclosure is not intended to be limited to the implementations shown, but is to be accorded the widest possible scope consistent with the principles and features disclosed herein.
Cytokines, which are signal proteins and mediators of an immune response to an inflammation, are secreted by a variety of cells, including lymphocytes, granulocytes, macrophages, endothelial cells, fibroblasts, etc., among which T cell lymphocytes are the dominant agents that level up released cytokines in bloodstream. A major reason of cytokine secretion by lymphocytes is attributed to their clonal expansion, a phenomenon by which activated lymphocytes produce more of themselves through mitosis division with the same antigen against a specific pathogen. Hence, controlling such mitosis would be of interest in suppression of immune hyperactivation in patients infected by an inflammatory disease, such as COVID-19 patients.
But, all medical procedures for the treatment of COVID-19 infection, up to now, are just limited to chemical drugs. All of scientists believe that a major challenge impacting mortality of COVID-19 patients is an out-of-control immune system activation and a subsequent cytokine production. During this process, adaptive an exemplary immune system is highly activated, and many of lymphocytes start to clonally expand, and hence many cytokines are also released. So, any ability to harness this cytokine storm and calm down an immune outrage is helpful. While the most infected battleground for immune hyperactivation in COVID-19 infected patients is their lung tissue, the only medical treatment for suppression of hypercytokinemia is based on immunosuppressor drugs that systemically dampen immunity with many unavoidable negative side effects such as increasing risk of sepsis, calcium metabolism, kidney disorders, etc.
Herein, an in-vitro and an in-vivo implementation of a method for suppressing clonal expansion of highly activated and proliferative lymphocytes is described. An exemplary method may include applying an alternating electric field (AEF) to highly activated and proliferative lymphocytes; thereby, resulting in electrically stimulating highly activated and proliferative lymphocytes leading to reducing mitosis division of such lymphocytes and consequently, reducing cytokine production by such lymphocytes. Herein, “highly activated (hyperactivated) lymphocytes and/or highly proliferative lymphocytes” may refer to lymphocytes of an exemplary immune system of a patient infected with an inflammatory diseases, such as COVID-19. Exemplary hyperactivated lymphocytes may be highly proliferative and divide rapidly, so a number of lymphocytes may rapidly increase in an infected organ or tissue. Furthermore, hyperactivated lymphocytes may release large amounts of cytokines in an infected organ or tissue; thereby, resulting in a cytokine storm there. Lymphocyte activation/hyperactivation occurs when lymphocytes (B cells or T cells) are triggered through antigen-specific receptors on their cell surface. This causes the B cells or T cells to proliferate and differentiate into specialized effector lymphocytes. An exemplary method for suppressing clonal expansion of highly activated and proliferative lymphocytes may include exposing a medium, organ, or tissue within a patient's body to an AEF, where the medium, organ, or tissue within the patient's body may include a plurality of highly activated and proliferative lymphocytes caused by an inflammatory disease, such as COVID-19 infection.
Herein, an exemplary method, system, and apparatus is described for preventing and/or suppressing cytokine storm in a patient's body. An exemplary method, system, and apparatus may be utilized for locally preventing and/or suppressing cytokine storm in a target location of patient's body involved with a hyperactivation of immune system there. In an exemplary embodiment, an exemplary method, system, and apparatus may be utilized to suppress clonal expansion of highly activated and proliferative lymphocytes and consequently, reduce cytokines releasing by lymphocytes. An exemplary method may include electrically stimulation of highly expanding lymphocytes by an alternating electric field (AEF) during a hyperactivation of an immune system caused by an inflammation, such as COVID-19 infection. An exemplary method may include applying AEF to a target location of highly expanding lymphocytes, for example, lung of a COVID-19 infected patient by delivering low intensity and intermediate frequency electric field to the target location. An exemplary applied AEF may disrupt mitotic spindle assembly of highly dividing cells so that abnormally dividing cells with prolonged mitosis phase (during their cell cycle) undergo apoptosis. Since applying AEF may have an antimitotic mechanism, the most affected cells may include highly proliferative ones, such as highly expanding lymphocytes, while healthy cells with a low rate of division may not be damaged during such electrical stimulation. In an antimitotic mechanism, AEF may exert directional forces on polar microtubules and interfere with assembly of normal mitotic spindle. Such interference with microtubule dynamics may result in abnormal spindle formation and subsequent mitotic arrest or delay. Since mitosis may not occur for lymphocytes that are not activated, therefore, healthy cells may remain immune from AEF effect.
On this basis, AEF may be safely applied for each patient to suppress highly activated and expanding lymphocytes and consequently reducing an amount of released cytokines into bloodstream. Currently, suppression of cytokine storm in COVID-19 infected patients is implemented using systemic administration of immunosuppressor drugs that debilitate entire immune system. Whereas, AEF stimulation consistent with exemplary embodiments may be applied locally to an organ affected by COVID-19 virus, i.e., lung tissue without any effect on the other immune cells by impacting only highly expanding lymphocytes in a target highly infected organ, e.g., lung tissue.
In an exemplary implementation, an exemplary method for suppressing clonal expansion of hyperactivated lymphocytes is described.
In an exemplary implementation, exemplary method 100 may be conducted in-vitro for suppressing clonal expansion of hyperactivated lymphocytes in a biological sample as an exemplary medium including a plurality of hyperactivated proliferative lymphocytes.

In an exemplary implementation, step 102 may include putting a medium including a plurality of hyperactivated proliferative lymphocytes in contact with set of electrodes 204. In an exemplary implementation, putting a medium including a plurality of hyperactivated proliferative lymphocytes in contact with set of electrodes 204 may include placing a biological sample including a plurality of hyperactivated proliferative lymphocytes on electrode heads of set of electrodes 204.

In an exemplary embodiment, set of electrodes 204 may include an even number of electrodes, including a plurality of electrode pairs, where each electrode pair of set of electrodes 204 may be configured to be connected to a respective signal output and a respective ground output of an exemplary AC function generator device. Thereby, an AEF field may be generated between electrodes of each electrode pair by applying an AC voltage between two electrodes of each electrode pair utilizing the AC function generator device. In an exemplary implementation, the generated AEF may exert force on alpha and beta tubulin heterodimers during formation of mitotic spindle while cell division of hyperactivated proliferative lymphocytes is being done. An exemplary exerted force may disrupt mitotic spindle and dividing cells may undergo apoptosis; thereby, a suppression in mitosis of hyperactivated proliferative lymphocytes may occur.
In an exemplary implementation, generating an AEF within an exemplary medium being placed on electrode heads of set of electrodes 204 (step 114) may include applying an AC voltage to set of electrodes 204 utilizing the AC function generator device. In an exemplary embodiment, applying the AC voltage to set of electrodes 204 utilizing the AC function generator device may include applying the AC voltage between two subsets of set of electrodes 204 utilizing the AC function generator device. In an exemplary embodiment, two subsets of set of electrodes 204 may include a first subset of set of electrodes 204 and a second subset of set of electrodes 204. In an exemplary embodiment, the first subset of electrodes 204 and the second subset of electrodes 204 may include an equal number of electrodes from set of electrodes 204. In an exemplary embodiment, the first subset of electrodes 204 may include half of electrodes of exemplary set of electrodes 204, and the first subset of electrodes 204 may be configured to be connected to signal output of an exemplary AC function generator device. Furthermore, the second subset of electrodes 204 may include the other half of electrodes of exemplary set of electrodes 204, and the second subset of electrodes 204 may be configured to be connected to ground output of an exemplary AC function generator device allowing for applying the AC voltage between the first subset of electrodes 204 and the second subset of electrodes 204. In an exemplary embodiment, electrodes of the first subset of electrodes 204 and the second subset of electrodes 204 may not be in a specific or pre-determined order and may alternate during applying the AC voltage by replacing one electrode of the first subset of electrodes 204 connected to an exemplary signal output by another one electrode of the second subset of electrodes 204 connected to an exemplary ground output. In an exemplary embodiment, electrodes of the first subset of electrodes 204 may include half of electrodes of exemplary set of electrodes 204 placed next to each other, and electrodes of the second subset of electrodes 204 may include the other half of electrodes of exemplary set of electrodes 204 also placed next to each other.
In an exemplary implementation, applying an AC voltage to set of electrodes 204 utilizing the AC function generator device may include applying an AC voltage in a range between 0.5 V/cm and 7 V/cm with a constant frequency in a range between 50 kHz and 200 kHz to set of electrodes 204 utilizing the AC function generator device. In an exemplary implementation, applying an AC voltage to set of electrodes 204 utilizing the AC function generator device may include applying an AC voltage of 3 V/cm with a constant frequency of 100 kHz to set of electrodes 204 utilizing the AC function generator device.
In an exemplary implementation, electrically stimulating an exemplary plurality of hyperactivated proliferative lymphocytes within an exemplary medium being placed inside liquid holder 208 on electrode heads of set of electrodes 204 (step 104) may further include stimulating the hyperactivated proliferative lymphocytes with respective mitotic spindles aligned in a plurality of directions by periodically changing a direction of the generated AEF in a plurality of directions within the medium (step 116). It should be noted that in process of cell mitosis, for example, in mitosis of lymphocytes, an orientation of a mitotic spindle may determine a plane of cell division. Spindle orientation of cells appears to be a consequence of cell elongation along a zero-force direction. In a state of no external force applied to cells, cells may have mitotic spindles aligned to various directions, where by applying an external force to cells, cells may align their mitotic spindle perpendicular to the external force. So, applying an external force to cells, for example, applying an electrical field (e.g., AEF) to cells, may lead to arrange mitotic spindles of cells in directions dictated by the external force. It should be noted that the applied AEF may affect highly activated lymphocytes only if a direction of the applied AEF is aligned with a mitotic spindle of lymphocytes being divided. In an exemplary embodiment, a direction of the applied may be changed periodically leading to increase a probability of alignment of the applied AEF direction with a direction of lymphocytes' mitotic spindle. In an exemplary implementation, periodically changing a direction of the generated AEF in a plurality of directions within the medium may include changing a direction of the generated AEF by an amount of degrees, for example, 45 degrees (45°) clockwise or counterclockwise per each time step of a set of time steps, for example, per second.
In an exemplary implementation, periodically changing a direction of the generated AEF in a plurality of directions within the medium (step 116) may include periodically changing arrangement of electrodes of first subset of electrodes 312 and second subset of electrodes 314 as shown in exemplary arrangements 304-310. In an exemplary implementation, periodically changing a direction of the generated AEF in a plurality of directions within the medium (step 116) may include periodically changing electrodes of first subset of electrodes 312 and second subset of electrodes 314 by replacing at least one electrode of first subset of electrodes 312 with at least one electrode of second subset of electrodes 314; thereby, resulting in forming various arrangements of electrodes of first subset of electrodes 312 and second subset of electrodes 314.
In an exemplary implementation, periodically changing a direction of the generated AEF in a plurality of directions within the medium (step 116) may further include applying AEF in various directions by applying an electrical voltage between first subset of electrodes 312 and second subset of electrodes 314 with various formed arrangements.
It should be noted that cells may have mitotic spindles in various alignments. So, changing an AEF generated direction periodically in various cycles (e.g., cycles 324-330) may lead to increase a chance of parallelism between the AEF direction and an axis of cell division. Referring to
In an exemplary implementation, periodically changing a direction of the generated AEF in a plurality of directions within the medium (step 116) may include periodically switching a direction of the generated AEF from a direction to another every time interval. In an exemplary implementation, periodically changing a direction of the generated AEF in a plurality of directions within the medium (step 116) may include periodically switching a direction of the generated AEF from a direction to another every second.

In this example, an AEF stimulation biochip similar to exemplary biochip 200 was prepared. A glass substrate was cleaned using piranha solution (H2SO4:H2O2 with a volume ratio of 2:1, respectively). Then, a layer of Cr with a thickness of about 20 nm was deposited on the substrate using RF sputtering procedure and a layer of Au with a thickness of about 100 nm was deposited on the Cr layer using RF sputtering procedure. The Cr layer was used in order to enhance the Au layer adhesion to the glass substrate. Using standard photolithography, 8 electrodes were patterned on surface of Au coated glass. The patterned electrodes were passivated (electrically insulated) using a 4 μm layer of polydimethylsiloxane (PDMS) by spin coating at 6000 rpm for 5 minutes. The biochip contains eight electrodes designed in a circular pattern with an inner radius of 2 cm to attain symmetrical electric field distribution in four directions of electric field stimulation.
In this example, peripheral blood mononuclear cells (PBMCs) were isolated from healthy donors, followed by artificially being activated using lymphocyte expansion kits for mimicking lymphocytes clonal expansion by activating PBMCs. It should be noted that lymphocytes are one of subsets of white blood cells with mitosis capability. When lymphocytes are activated by external physicochemical signals, they form a cluster of cells and then are expanded. In case of T and B lymphocytes, such a phenomenon is called clonal expansion in which first activated cell produces many copies of itself with the same antigen properties. In order to mimic expansion of WBCs, T and B activation kits were utilized to artificially trigger expansion of lymphocytes in PBMCs of blood in-vitro.
Here, whole blood was obtained through a venipuncture technique from each person. PBMCs were isolated from the whole blood using density gradient centrifugation (DGC) method and then divided into four groups, including a first group of non-activated PBMCs without any external stimulation (intact WBCs are imaged as the control group), a second group of activated PBMCs, in which WBCs may began to expand using commercial activating kits for T and B cells, a third group of activated PBMCs stimulated by AEF (activated PBMCs+AEF), and a fourth group of activated PBMCs treated by Dexamethasone with a dosage of 4 mg/ml (PBMC+Dexamethasone). In this regard, an effect of AEF in suppressing clonal expansion would also be compared to dexamethasone (conventional immunosuppressor drug). For activation of lymphocytes, isolated PBMCs were cultured inside a cell culture medium and their lymphocytes were activated using an expansion kit. Activated cells were incubated for 5 days to ensure lymphocytes activation. For AEF stimulation of activated cells, activated cells were dropped on surface of exemplary fabricated biochip in EXAMPLE 1 hereinabove and stimulated using AEF stimulation according to exemplary method 100 for 48 hours. AEF stimulation of cells caused apoptosis in clusters of activated lymphocytes during cell division. FOR AEF stimulation of activated cells, exemplary fabricated biochip was connected to an RF function generator at 100 kHz sinusoid of 3 V/cm electric field amplitude. Effect of applying AEF on suppressing expansion of lymphocytes was evaluated by time-lapse imaging, viability, and apoptosis assays as well as flow cytometry technique. Moreover, amount of three major cytokines (TNF-alpha, INF-gamma, IL-6) after AEF stimulation was also measured using ELISA method.
Time-Lapse Imaging Analysis:
To analyze effect of AEF stimulation to suppress proliferation of exemplary activated lymphocytes, time-lapse imaging from PBMCs at different times was used.
For more elaboration, AEF stimulation was applied on activated immune cells after 5 days. During these five days, clonal expansion clusters of immune cells were formed. Then, cluster size and their abundance were imaged and analyzed after 48 hours of AEF treatment via time-lapse microscopy.
Viability of Stimulated Clusters and Non-Activated WBCs:
AO/PI staining as well as apoptosis assay by Annexin V/PI flow cytometry technique was carried out to analyze correlation between cellular viability and size reduction of treated clusters. Viability and apoptosis assays were performed separately on lymphocytes, including B and T cells.
Additionally, effect of AEF on non-activated white blood cells was evaluated by live/dead staining and apoptosis assay.
Trajectory of WBCs as well as their displacement and velocity were also analyzed for non-activated WBCs in the presence and absence of AEF.
For further clarification, effect of electric field on invasive function of WBCs toward pathological threats was assessed. Time-lapse imaging was utilized to inspect interaction of WBCs with exemplary foreigner MDA-MB-231 cells. Due to HLA mismatch between MDA-MB-231 cells and donor WBCs, it is supposed that cytotoxic T cells (CTLs) as well as natural killer cells (NK cells) are activated and invade the MDA-MB-231 cells.
Effect of AEF on Lymphocyte Subsets Analyzed by Flow Cytometry:
Flow cytometry technique was employed to investigate detailed effects of AEF on each subset of lymphocytes. Both of B and T cell activation and expansion kits were simultaneously applied to a blood sample of a healthy donor. Cells were then (after 5 days) treated with AEF stimulation for 4 days, and number of CD8 and CD4 positive cells (T cell markers) and CD19 cells (B cell marker) were counted by a flow cytometer. Obtained results were compared with similar results for activated but non AEF treated cells as a control group.
Based on
Inspecting Cytokine Reduction after Electric Field Treatment:
Cytokine production by immune cells was analyzed in both groups of activated control and AEF-treated cells. Firstly, cells were activated for 5 days. In the activated PBMC+AEF group, cells were under AEF stimulation for about 4 days. During these 4 days, non-AEF treated group was just kept in an incubator. At the end of test, solution medium of both groups was collected and analyzed by enzyme linked immunosorbent assay (ELISA) method.
Although many cytokines are produced and play functional roles in post-activated immune cells, there are three main cytokines, including IL-6, TNF-α, and IFN-γ that are produced by lymphocytes and play the main role especially in COVID-19 disease.
In this example, in-vitro AEF stimulating of WBCs derived from COVID-19 patients with severe inflammation and cytokine storm was carried out according to exemplary method 100 utilizing an exemplary fabricated biochip according to EXAMPLE 1 hereinabove similar to exemplary biochip 200. Human blood samples were collected from five patients with COVID-19 disease to assess efficacy of applying alternating electric field on suppressing activation and expansion of immune cells and consequent reduction in cytokine production. Patients had not received any medication prior to blood sampling. After blood sampling and isolation of WBCs (PBMCs) using density gradient centrifugation method, cells were divided into two cohorts of a control group (without AEF treatment) and a group of electrically stimulated cells. Both groups were under analysis for 4 days.
Time-lapse imaging from samples of patients was done via immunofluorescence imaging. An exemplary sample was divided into two parts and each part was stained separately for analyzing and observing T cells clusters and B cells clusters separately.
For AEF stimulation, lymphocytes were cultured in blood serums and were stimulated by AEF for 4 days. Size of produced clusters was analyzed after AEF stimulation.
