Background: Type 2 diabetes (T2D) is a chronic metabolic disorder in which beta-cells are destroyed. The islet amyloid polypeptide (IAPP) produced by beta-cells has been reported to influence beta-cell destruction. Objective: To evaluate if IAPP can act as an autoantigen and therefore, to see if CD8 + T-cells specific for this protein might be present in T2D patients. Methods: Peripheral blood ...
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...
CD8(+) T cells play important roles in anti-tumor immunity but distribution profile or functional characteristics of effector memory subsets during tumor progression are unclear. We found that, in oral squamous carcinoma patients, circulating CD8(+) T cell pools skewed toward effector memory subsets with the distribution frequency of CCR7(-)CD45RA(-)CD8(+) T cells and CCR7(-) CD45RA(+)CD8(+) T ...
background: lymphocyte subsets enumeration is considered prominent in the management of primary and acquired immunodeficiency disorders. because of local variations due to race, age, gender, and environmental conditions on lymphocyte subsets, and to improve the accuracy of interpretation of laboratory findings, reference intervals must be determined in every population. objective: to establish ...
CD8⁺cytotoxic T cells, CD4⁺ helper and regulatory cells interact differently with cancer. CD8⁺ cytotoxic recognize the antigens presented by cancer kill in various ways. recruit other immune promote them to destroy cells. On hand, suppress cell proliferation response of both This suppressive mechanism often leads progression These cell-cancer interactions can render conventional treatments inef...
