variety of positive as well as negative regulatory signals are provided by antigen presenting cell in particular by dendritic cells. in this research, we studied the capacity of dendritic cells to expand antigen-specific t regulatory cells.we also investigated the role of tgf-beta in induction inhibitory functions of dendritic cells in mixed leukocyte reactions. dendritic cells were generated f...
In the context of chronic antigen exposure in chronic viral infections and cancer, T cells become exhausted/dysfunctional. These exhausted T cells exhibit defective proliferative capacities and cytokine production, but are not totally inert and may exert lytic functions. Importantly, exhausted T cells upregulate multiple inhibitory receptors/immune checkpoints that bind to their ligands express...
Background: Programmed cell death protein-1 (PD-1)/PD-L1 pathway is one of the immune checkpoint pathways involved in regulation of the immune responses and suppression of anti-tumor defense. PD-1/B7-H1-blocking antibodies improve immune responses such as cytotoxic activity of CD8+/CD4+T cells and also increase mortality of tumor cells; however their use is accompanied by adverse effects in pat...
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...
In the article was studied effects of flavonol quercetin on indices adaptive immune response in experimental animals 14 th day bacterial-immune periodontitis development. Indices protection were determined by relative number lymphocytes with CD3+, CD4+, CD8+, CD19+, CD16+ and immunoregulatory index (CD4+ / CD8+) intact inflammatory process development periodontal tissues as well therapeutic que...
