Experimental conditions have been established for the elicitation of an allogeneic effect on the adoptive transfer secondary anti-2,4-dinitrophenyl (DNP) antibody response in mice. Thus, spleen cells from DNP-keyhole limpet hemocyanin (KLH)-primed mice manifest good secondary anti-DNP responses to a challenge with DNP-KLH, but not with DNP-bovine gamma globulin (BGG), after adoptive transfer to...

backgrounds: seminoma is frequently observed in human and canine testes especially in cryptorchids. canine and human seminomas are typically associated with leukocytic infiltration. objectives: we aimed to identify the type of lymphocytes that infiltrate to seminomas. methods: tumor infiltrating lymphocytes were evaluated by immunohistological techniques in 5 dogs with diffuse seminoma. routine...

In the course of carrying out a comprehensive assessment state environment and health population city Kentau adjacent territories, study mutagenic activity drinking water soil samples taken in territory settlements, background comparison was carried out. study, it revealed that individual extracts soils cause significant increase frequency chromosomal abnormalities cultures human peripheral blo...

The two-colour flow cytometry method applied in a routine enumeration of peripheral blood T lymphocyte subsets reveals that in some patients the entire population of CD4+ lymphocytes seems to express CD8 determinants as well. However, expression of the CD8 antigens on the cell surface is much lower in comparison with typical CD8+ cells. Moreover, in one-colour staining with an anti-CD8 antibody...

Background: Iron is an essential trace element in cell proliferation. Several investigations demonstrate that iron deprivation inhibits cell proliferation. However, the impact of iron on telomerase activity of activated lymphocytes remains unexplained to date. Objective: In this study, the effect of iron on the proliferation and telomerase activity of lymphocytes stimulated by phytohemagglutini...

Human T-cell lymphotropic virus type 1 (HTLV-1) is associated with adult T-cell leukemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and HAM/TSP is the most common clinical manifestation of the virus. HAM/TSP is an inflamma...

spontaneous abortion is the most common complication of pregnancy. several lines of evidence indicate that immunologic effector cells may play a role in the pathogenesis of idiopathic repetitive abortions. leukocytes form a substantial proportion of stromal cells in decidua and the endometrial granulated lymphocytes (egl) is the predominant decidual leukocyte population in the first trimester o...

At varying intervals after immunizing infections of adult BALB/c mice with lymphocytic choriomeningitis (LCM) virus, splenic lymphocytes were tested for their ability to either elicit acute LCM or protect against lethal intracerebral LCM virus challenge when transferred to syngeneic recipients that were, respectively, virus carriers induced by cyclophosphamide-induced immunosuppression and norm...

allergic asthma is a complex and chronic inflammatory airway disease. interleukin-17 is a pro-inflammatory cytokine which plays critical role in the pathogenesis of allergic asthma. it has been reported that β-arrestin2 regulated the development of allergic asthma at a proximal step in the inflammatory cascade. in this study, the influence of β-arrestin2 on interleukin-17 production and express...

Background: Covid-19 is a very contagious and quickly spreading viral infection, caused by corona virus SARS-COV-2 which was originally reported in China on December 5, 2019. It confirmed as pandemic WHO March 11, 2020. This disease yet under research. has variable severity includes no symptoms to pneumonia. can cause death of the patient. Aim: To evaluate association Lymphopenia with COVID 19 ...
