    Opis:
    Introduction. Human T-cell lymphotropic virus types 1 and 2 (HTLV-1 & 2) are frequent co-pathogens among immunosuppressed individuals, particularly HIV/AIDS infected persons. Dual infected persons usually present with false normal or high CD4+ T cells count as a result of the ability of HTLV to induce clonal proliferation of CD4+ T lymphocytes. There is paucity of information on this clinical entity in Nigeria. Aim. This study aimed to determine the seroprevalence of HTLV-1/2 and associated cellular immune response among antiretroviral naïve and experienced HIV infected persons at Bauchi State, Nigeria. Material and methods. One hundred and eighty two (182) HIV seropositive patients’ blood samples were analyzed for anti HTLV-1/2 IgM and IgG antibodies using ELISA while CD4+ T cells were counted using Flow cytometry technique. Socio-demographic data of the subjects and clinical history were obtained via questionnaire and medical records, respectively. Results. The seroprevalence of anti-HTLV-1/2 was 14%. This comprised 76 (41.8%) males and 106 (58.2%) females. Six (3%) were seropositive for both ant-HTLV -1&2 IgM and IgG. Of the total positive for anti-HTLV-1/2, 20 (25%) ART-naïve and 6(5.9%) ART-experience subjects. Whole blood CD4+ T cell count was significantly high in HTLV-1/-2 IgG/IgM seropositive subjects compared to their HTLV-1/-2 negative counterpart. Conclusion. All subjects (100%) who were HTLV-1/-2/HIV co-infected had normal to higher CD4+ T cell counts. It is suggested to be very careful in using only CD4+ counts to monitor HIV progression or as indicators for ART.

    Opis:
    The main aim of this study was to compare selected nonspecific immunity parameters in 14 allergic and 12 healthy horses. Each animal was assessed according to the following parameters: in vitro functional capacity of phagocytic cells using the nitro blue tetrazolium chloride reduction test, both spontaneous (NBT) and zymozan stimulated (NBTs), and ingestion capacity of phagocytic cells using a phagocytic index test (IF) and percentage of phagocytosing neutrophils activity (%KF). Differences were demonstrated between the group of allergic horses, especially with severe allergy symptoms, and healthy horses in NBTs values, with higher values in healthy horses. The values of the phagocytic index were significantly higher in horses with allergy.

    Opis:
    The objective of this study was to determine the stimulating effect of the Inter Yeast S dietary supplement on selected parameters of specific and non-specific humoral and cellular immunity in lambs. The study involved 32 lambs aged 30±3 days, divided into two equal groups: I - control, and II - experimental. Experimental group animals were fed a C-J concentrate mixed with a prebiotic, the Inter Yeast S, commercially available, containing dried brewer's yeast Saccharomyces cerevisiae in the amount of 3 g/kg of the concentrate. At the beginning of the experiment (day 0) and on the 15th, 30th and 60th day of the study, blood was sampled from the jugular vein to determine selected parameters of biochemical, specific and non-specific humoral and cellular immunity in lambs (total protein levels, gamma globulin levels, lysozyme activity, ceruloplasmin activity, proliferative response of blood lymphocytes (MTT) after stimulation with LPS or ConA, the metabolic activity (RBA) and potential killing activity (PKA) of phagocytes). As regards humoral immunity parameters, significantly higher gamma globulin levels and higher lysozyme and ceruloplasmin activity were found in blood serum of experimental lambs administered the Inter Yeast S, compared with those determined in control lambs not fed the supplement. No statistically significant differences in serum total protein were found between the control and experimental groups. An analysis of cellular immunity indicators revealed significantly higher levels of RBA and PKA, and higher proliferative response of blood lymphocytes (MTT) after stimulation with LPS and ConA in the experimental group, compared with those observed in the control group.

    Opis:
    Introduction. Structural glycans have great biological significance and are involved in signaling and cell communication of the immune system. They are attached to proteins and lipids in an enzymatic process called glycosylation where glycosyltransferase and glycosidases bind sugar residues and lead to the formation of bioconjugates. Aim. In this paper we describe the importance of glycosylation in the immune system and its changes in diseases. Material and methods. This review was performed according to systematic literature search of major bibliographic databases. Results. Proper glycosylation ensures the functioning of the organism, however, defects in structural glycans of immune system changes their properties and can lead to disorders and further to autoimmune diseases. It has been also proven that glycosylation of autoimmune system is changed during cancer. In this paper we described types of structural glycans, significance of glycosylation of selected components of the immune system and its modifications in disorders. Conclusions. Knowledge about changes in the glycosylation in diseases is the key to understanding the processes of autoimmune diseases and may allow the development of new treatments in the future.
