PATHOLOGY

Detailed explanation-1: -CD4+ T cells help antiviral CD8+ T cells in two main ways: they maximize CD8+ T cell population expansion during a primary immune response and also facilitate the generation of virus-specific memory CD8+ T cell populations. In addition to their helper functions, CD4+ T cells contribute directly to viral clearance.

Detailed explanation-2: -Helper T-cells are a type of immune cell. When they sense an infection, they activate other immune cells to fight it. They may activate cytotoxic T-cells or they may activate B-cells, which produce antibodies. Your helper T-cells are one the most important types of cells involved in your adaptive immune response.

Detailed explanation-3: -CD4+ T cells, or helper T cells, are one type of lymphocyte that helps coordinate the immune response against infection and disease. They interact and activate other cells in the immune system.
