Since CD4 receptor binding is the most obvious step in HIV infection, gp120 was among the first targets of HIV vaccine research. Efforts to develop HIV vaccines targeting gp120, however, have been hampered by the chemical and structural properties of gp120, which make it difficult for antibodies to bind to it. gp120 can also easily be shed from the surface of the virus and captured by T cells ...
The surface expression of this complex shows high variability, particularly in relation to the polymorphism of GPIa subunit gene. Different opinions exist on the importance of C - T point mutation at position 807, which is believed to be associated with the risk of myocardial infarction or ischemic stroke. [3]
T cells are one of the important types of white blood cells of the immune system and play a central role in the adaptive immune response. T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface. T cells are born from hematopoietic stem cells, [1] found in the bone marrow.

T H 1 cells which produce interferon gamma and lymphotoxin alpha, T H 2 cells which produce IL-4, IL-5, and IL-13. A third category called T helper 17 cells (T H 17) were also discovered which are named after their secretion of Interleukin 17. CD8 + cytotoxic T-cells may also be categorized as: [5] T c 1 cells, T c 2 cells.

The T-cell marker Thy-1 and acetylcholinesterase, as well as both intestinal and placental alkaline phosphatases, are known to be GPI-linked and are released by treatment with PLC. GPI-linked proteins are thought to be preferentially located in lipid rafts , suggesting a high level of organization within plasma membrane microdomains.
Subsequently, the primed cells will differentiate either into effector cells or into memory cells that can mount stronger and faster response to second and upcoming immune challenges. [2] T and B cell priming occurs in the secondary lymphoid organs (lymph nodes and spleen). Priming of naïve T cells requires dendritic cell antigen presentation.
