  2. Pathophysiology of HIV/AIDS - Wikipedia

    en.wikipedia.org/wiki/Pathophysiology_of_HIV/AIDS

    The CD8 + T cell response is thought to be important in controlling virus levels, which peak and then decline, as the CD4 + T cell counts rebound. A good CD8 + T cell response has been linked to slower disease progression and a better prognosis, though it does not eliminate the virus. [3] During the acute phase, HIV-induced cell lysis and ...

  3. Cytotoxic T cell - Wikipedia

    en.wikipedia.org/wiki/Cytotoxic_T_cell

    Antigen presentation stimulates T cells to become either "cytotoxic" CD8+ cells or "helper" CD4+ cells.. A cytotoxic T cell (also known as T C, cytotoxic T lymphocyte, CTL, T-killer cell, cytolytic T cell, CD8 + T-cell or killer T cell) is a T lymphocyte (a type of white blood cell) that kills cancer cells, cells that are infected by intracellular pathogens such as viruses or bacteria, or ...

    en.wikipedia.org/wiki/Diffuse_infiltrative_lymph...

    Diffuse infiltrative lymphocytosis syndrome (DILS) is a rare multi-system complication of HIV believed to occur secondary to an abnormal persistence of the initial CD8+ T cell expansion that regularly occurs in an HIV infection. [1] This persistent CD8+ T cell expansion occurs in the setting of a low CD4+/CD8+ T cell ratio and ultimately ...

    The presence of a CD8+ cell noncytotoxic anti-HIV response (CNAR) was first reported in 1986 by researchers in the laboratory of Dr. Jay Levy at the University of California San Francisco (UCSF). [2] It was recognized that CD8+ cells from HIV-infected individuals can suppress HIV replication without directly killing the infected cells. [3]

    At presentation, 31 patients with CD8+ TLPD were 29–89 years old (average 52.1 years); 23 were male, 8 were female; 26 had nodules, 5 had plaques; 28 had a single lesion, 2 had bilateral lesions, and 1 had multiple lesions; 18 had a single lesion on the ear, 3 had a single lesion on the nose, 1 had a single lesion on the leg, 4 had a single lesion on the foot, 2 had a single lesion on the ...

  7. Antigen presentation - Wikipedia

    en.wikipedia.org/wiki/Antigen_presentation

    Antigen processing and presentation in MHC-I pathway. Cytotoxic T cells (also known as T c, killer T cell, or cytotoxic T-lymphocyte (CTL)) express CD8 co-receptors and are a population of T cells that are specialized for inducing programmed cell death of other cells. Cytotoxic T cells regularly patrol all body cells to maintain the organismal ...
