6. The dimensions of human and murine CD8 T lymphocyte diversity
Abstract : The adaptive immune system generates and maintains a pool of CD8+ T cells with an almost limitless specificity with the purpose of maintaining homeostasis. Upon antigen encounter, CD8+ T cells undergo functional diversification and give rise to daughter cells. READ MORE

7. Leucine-rich repeats and immunoglobulin-like domain (LRIG) proteins : possible prognostic markers in vulvar squamous cell carcinoma, endometrial carcinoma, and oropharymgeal squamous cell carcinoma
Abstract : The human leucine-rich repeats and immunoglobulin-like domain (LRIG) gene family comprises three genes, LRIG1, LRIG2 and LRIG3, which encode the LRIG1, LRIG2 and LRIG3 proteins, respectively. Previous stidies have revealed the different prognostic roles of these proteins in different cancers, and it has been shown that LRIG1 functions as a tumour suppressor in certain cancers via its negative regulation of several receptor tyrosine kinases.

8. Beta-chemokine and CD8+ T-cell noncytotoxic anti-HIV/SIV activity
Abstract : A small number of individuals remain uninfected despite repeated exposure to HIV. A number of viral and host factors are thought to account for this resistance. The cell-mediated immune response is likely to be important in controlling HIV/SIV infections. READ MORE

9. Human intraepithelial lymphocytes : a comparative study of phenotype, morphology, and functional properties of intraepithelial lymphocytes in gut and oral mucosa
Abstract : Human intraepithelial lymphocytes (IEL) constitute a unique cell population situated in the first line of defense of the alimentary tract. Here they are continuously exposed to a massive antigenic load of high complexity. However, different conditions prevail along the alimentary tract. READ MORE

10. CD8+ T cell specificity in thymic selection and in the recognition of antigen
Abstract : Specificity mediated by the T cell receptor (TCR) is of fundamental importance for the ability of T cells to function, and regulate humoral immunity and effector mechanisms of the innate immune system. T cells recognize composite molecules consisting of products of the major histocompatibility complex (MHC) class I or class 11 loci, in complex with a short peptide fragment derived from endogenous or antigenic proteins.
