Cellular And Humoral Immunity

Abstract The purpose of these studies was to determine the indicators of cellular and humoral immunity of calves. Compared to calves obtained from untreated cows, the number of T-lymphocytes in young calves born from cows treated with Timolin increased the level of T-cells to 32.9%, while using Timosplenin 45%. As a result of the use of immunomodulators in treating cows with ketosis in mothers, the relative content of T-lymphocytes in the blood of calves born from them increased when using the drug Leucogen by 1.7 times, Timosplenin by 2.3 times, Timalin in 2.2 times. The use of Leucogen for cows with ketosis contributed to an increase in the percentage of B cells in the blood of calves born by 23%, Timosplenin 83%, and Timalin 42%. At the same time, the absolute number of B-lymphocytes in the treatment of “Leucogen” increased 1.9 times and reached the level of healthy calves, in the treatment with the preparations “Timosplenin” and “Timalin” - the increase was, respectively, 3.0 and 2.3 times and was higher this indicator in young animals born from healthy calves. Thus, the inclusion of dry immunomodulators in the treatment regimen of patients with ketosis leads not only to normalization of metabolism, but is also accompanied by an increase in the level of cellular immunity factors in calves born from them. Under the influence of “Leucogen,” the percentage of lymphocytes was normalized, whereas with the introduction of “Timalin” and “Timosplenin,” the content of this type of cells in newborn calves even exceeded those in healthy young.

Despite a huge number of studies, the uniqueness of antiparasitic immunity is so great that there is still insufficient knowledge of the factors contributing to the manifestation of the characteristics of immunity in mixed parasitic diseases of rabbits. Therefore, the question of the influence of the association of pathogens Treponema cuniculi and Eimeria sp. on indicators of cellular immunity of rabbits is relevant. The study was conducted on 59 male rabbits age 3–5 months of the Californian breed, selected by analogy. Animal were separated into two groups: healthy animals (control group) and sick animals (research group). Intensity of invasion was determined by the method of the Mac-Master. It has been established that the level of damage of rabbits by spirochetosis and eimeriosis was, on average, 1155.17 ± 184.87 and 6668.97 ± 284.16 pathogens in 1 g of feces. The count of T- and B-lymphocytes was determined by the method of spontaneous rosette-formation with sheep erythrocytes. Parasitizing the association of pathogens Treponema cuniculi and Eimeria sp. was revealed a high number of leukocytes (1.22 times, P < 0.001), which increased mainly due to lymphocytes, which were 1.45 times higher (P < 0.001), as well as neutrophilic metamyelocytes – 1.48 times (P < 0.05), eosinophils – 1.68 times (P < 0.001) and basophils – 1.57 times (P < 0.001) compared with similar blood parameters of healthy animals. In the blood of sick rabbits, the absolute number of T-lymphocytes (1.56 times, P < 0.001) and B-lymphocytes (3.02 times, P < 0.001) was significantly higher in comparison with a low number of O-lymphocytes (3.46 times, P < 0.001) compared with the control. This indicates the redistribution of lymphocytes to cells that carry T and B lymphocyte receptors on the plasma membrane. The absolute number of T-lymphocytes became high due to T-helpers, which in these animals were higher both in absolute (1.87 times, P < 0.001) and percentage (by 9.18%, P < 0.001) compared to control. Moreover, the percentage of T-suppressors in the blood of rabbits of the experimental group was significantly lower on 5.46% (P < 0.05) compared with the same blood count of healthy animals. Such a redistribution of the T-cell population in the peripheral blood of this group of rabbits led to an increase in the immunoregulatory index by 1.64 times (P < 0.01) than in healthy ones. High IRI and the number of T-active lymphocytes (by 28.23%, P < 0.05) in the blood of rabbits with parasitism of the association of pathogens Treponema cuniculi and Eimeria sp. indicate increased immune system tension.

Introduction. Studies indicate the high pathogenetic significance of the immune component in the development of atherosclerosis. The aim of the study is a comparative assessment of immunological parameters in workers of petrochemical production with varying degrees of imbalance in lipid metabolism and the development of the atherosclerotic process. Materials and methods. Men working at an oil production enterprise in the Perm Region were examined. The observation group consisted of oil production operators with a diagnosis of atherosclerosis, the comparison group - with dyslipidemia syndrome. To determine the parameters of lipid metabolism, the results of a biochemical blood test were used. CD-immunogram parameters were identified by flow cytometry. Specific antibodies to benzene were determined by the allergosorbent method. Results. The results of a comparative study of fat metabolism confirmed violations of the physiological ratio of lipids in the blood of oil production workers, which were expressed in a significant imbalance in the levels of lipidogram. There was an increased level of specific IgG antibodies to benzene in the observation group in relation to the comparison group. An imbalance of cellular immunity was found, which was characterized by signs of indicators activation of cellular differentiation clusters. Conclusions. Studies of immune system compartments demonstrate excessive activation of cellular and humoral immunity in oil production workers under the influence of a combination of harmful production factors. The simultaneously formed imbalance of lipid metabolism is associated with various degrees of clinical manifestation of atherosclerotic disorders, with the influence of harmful production factors, aggressiveness of cellular and humoral immunity, and smoking.

The results of research on the influence of the elaborated complex immunotropic drug containing butafosfan, interferon, thistle and fat-soluble vitamins A, D3, E in the form of a liposomal emulsion on the activity of T- and B-cell chains of immunity in rats under the conditions of action on the body of oxidative stress are presented. It has been established that the introduction of 50% tetrachloromethane into the rats of the first and second experimental groups, with a dose of 0.25 ml per 100 g of body weight, causes oxidative stress in them which negatively affects the cellular immunity and functional activity of immunocompetent blood cells. Immunosuppressive effects of oxidative stress were manifested by a decrease in the blood of rats in the first and second experimental groups of the number of T- and B-lymphocytes and their regulatory subpopulations mainly on the 2nd and 5th day of the study. At the same time, in the blood of rats of the first experimental group in all research periods a decrease in the relative number of common, active and theophylline-resistant T-lymphocytes, as well as B-lymphocytes was observed with a noticeable increase in the number of their undifferentiated forms. At the same time, the obtained data suggest the positive effect of butafosfan, interferon, thistle and vitamins A, D3, E in the liposomal preparation on the relative amount of T- and B-lymphocytes and on the redistribution of avidity in the direction of strengthening the receptor field of plasma membranes immunocompetent cells. It was found that the normalization on the 2nd day of blood level in the second experimental group of common T-lymphocytes occurred due to the secondary forms of the blood and active T-lymphocytes by changes in the number of low-avid forms. In addition to the indicators characterizing the cellular immunity of rats, the components of the liposomal preparation showed regulatory influence on the humoral link of the immune response. In particular, on the 10th day of research in blood of rats of the second experimental group a tendency towards an increase in the relative number of B-lymphocytes and an increase in the number of cells with low and medium density of receptors was found, which, under the conditions of oxidative stress, indicates an increase in the body's ability to actively synthesize protective antibodies

Abstract Lactic dehydrogenase (LDH) was quantitated and the isozyme pattern studied in lymphocyte subpopulations from normal people and patients with chronic lymphocytic leukemia (CLL). Normal T lymphocytes differed from normal B lymphocytes in having greater total LDH activity (597.2 versus 252.1). Total LDH activity in CLL T cells (347.1) was lower than normal T cells., but not significantly different than normal B cells. Total LDH activity in CLL B cells (124.6) was lower then normal B cells and normal T cells. The isozyme pattern of normal T lymphocytes showed a higher activity in the LDH-1 band (26.7% versus 5.4%) but showed a lower activity in LDH-5 band (4.3% versus 16.3%) compared to normal B cells. Chronic lymphocytic leukemia T cells could be distinguished from CLL B cells by a high LDH-5 band (22.3% versus 7.6%) and from normal T cells by a high LDH-5 band (22.3% versus 4.3%) and a low LDH-1 band (7.3% versus 26.7%). CLL B cells could be distinguished from normal B cells by a low LDH-5 band (7.6% versus 16.3%). Thus, the LDH isozyme pattern distinguishes normal T lymphocytes from normal B lymphocytes, and normal T and B lymphocytes from CLL T and B lymphocytes.

Abstract Abstract 4352 Background and objectives: We have recently shown that memory B-lymphocytes from murine CMV immune donor animals adoptively transferred into immunodeficient mice were highly effective in protecting from a viral infection indicating a therapeutic potential of virus specific memory B-cells. These preclinical data provided evidence that a cell-based strategy supporting the humoral immune response might be effective in a clinical setting of post-HSCT immunodeficiency (Klenovsek et al., 2007, Blood 110: 3472–9). As adoptive transfer of B-cells has not been used before in a clinical setting, it is necessary to establish a technology for the generation of GMP-grade B-cell products. Methods: Starting from the leukapheresis of healthy donors, B-cells were purified by two different separation strategies using GMP-grade microbeads and the CliniMACS∧TM device. A one-step protocol was used for positive enrichment of B-lymphocytes with anti-CD19 microbeads. In a two-step enrichment protocol, first T-lymphocytes were depleted by anti-CD3 microbeads and the remaining fraction was positively selected by anti-CD19 microbeads. Results: The leukapheresis contained a mean of 9.0×10∧8 CD19-positive B-cells (4.5–12.4 ×10∧8). After the one-step positive purification strategy a mean purity of CD20∧+ B-lymphocytes of 78.1% with a recovery of 32–41% was obtained. With the two-step T-cell depletion/B-cell enrichment protocol we achieved a mean purity of 96.4 % (93.4–97.8%) with a slightly lower recovery of 14–37%. The absolute B-cell numbers obtained in the product were 1.3 to 4.0 ×10∧8 and 1.7 to 2.6 ×10∧8 for the one-step positive enrichment and the two-step protocol, respectively. Importantly, the absolute number of T-cells was lower in cell products after the two-step protocol (0.1 to 0.9 ×10∧6 T-cells) as compared to the one-step positive CD19-enrichment (1.6 to 3.4 ×10∧6 T-cells). Assuming a patient with 70 kg body weight, the B-cell products obtained after the combined CD3-depletion and CD19-enrichment contained less then 4×10∧4 T-lymphocytes/kg bodyweight, which is a critical threshold number of T-cells in haploidentical HSCT. The B-cell products showed antibody production after in vitro stimulation in a limiting dilution assay and showed excellent viability after cryopreservation. Conclusions: A GMP-grade B-cell product can be obtained with high purity and very low T-cell contamination using the two-step enrichment protocol based on CliniMACS∧TM technology.

The purpose of this study was to identify prognostically unfavorable immune and endocrine development criteria hysterical disorders. The study involved patients with hysterical personality development, hysterical neurosis and healthy donors. Immunological reactions were performed by standard methods, hormonal - immune enzyme analysis. Changes in cellular and humoral immunity in the form of a reduction in the absolute number of T- and B-lymphocytes, decrease the metabolic activity of neutrophils, the ratio of circulating immune complexes of different molecular weight, and lower cortisol levels indicate the involvement of the immune endocrine reactions in the pathogenetic mechanisms of the development of the protracted forms of conversion disorders, and confirm the need for surveys of the immune and hormonal status of patients suffering from hysterical personality development. Identified by the authors the changes in neuro-immune-endocrine system can be regarded as a prognostically unfavorable in the development of hysterical disorders, and involve the use of immunomodulators in the treatment of these diseases.

The aim of the study – to evaluate changes in cellular immunity in rhesus-sensitized women in response to IVIG administration and the prognostic effectiveness of a method for the prevention of isoimmunization in the next pregnancy. Materials and Methods. The study was performed on the basis of City Maternity Hospital No. 7" (Odesa) in 2014–2019. 37 rhesus-sensitized women were randomly splited in two clinical groups: main clinical group (n=19) where patients received human immunoglobulin for intravenous administration, and control group (n=18) where patients did not receive IVIG. Results and Discussion. The state of cellular immunity in rhesus-sensitized women is characterized by a moderate decrease in the absolute and relative indices of T-lymphocytes while increasing the number of B-lymphocytes. The NK cell population did not differ from the control group. When analyzing subpopulations of T-lymphocytes, it can be concluded that the number of T-helper cells is increased and the number of T-suppressors is proportionally reduced. These changes explain the increase in the number of B-lymphocytes as a result of increasing antigenic load on cell receptors. In the group of women who received IVIG therapy, the ratio of chances of normalization of cellular immunity was 18.41 (95 % CI 2.62–166.74), T-helper – 14.93 (95 % CI) 2.45–107.8), T-suppressors – 14.57 (95 % CI 2.13 –127.57) and B-lymphocytes – 31.87 (95 % CI 4.1–333.41). According to the ROC analysis, the quality of the statistical model of IVIG application corresponds to AUC = 0.843 (95 % CI 0.689–0.941) According to the ROC analysis, the level of β-lymphocytes in the compared AUC groups = 0.58 (95 % CI 0.405–0.742).
