Globotriaosylceramide (Gb(3)) is a cell surface-expressed natural resistance factor for HIV infection, but, its expression in human T-cells remains unknown. Therefore, Gb(3) in resting or activated CD4(+) T-cells was assessed by flow cytometry and thin layer chromatography of cell extracts. We found the majority of CD4(+) T-cells, whether resting or activated, do not express Gb(3) at significant levels (<2% positive cells). Thus, HIV treatment or prevention strategies must focus on development of soluble Gb(3) analogues for inhibition of HIV infection.

T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
