IMMUNOLOGY

Detailed explanation-1: -There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body’s own cells that have themselves been taken over by viruses or become cancerous.

Detailed explanation-2: -There are several types of T cells; the most common and well-known are the CD4+ T cells (helper T cells) and CD8+ T Cells (cytotoxic T cells, or killer T cells). T cells cannot recognize soluble, free antigens. T cells can only recognize protein-based, receptor-bound antigens.

Detailed explanation-3: -T cells and B cells T cells (thymus cells) and B cells (bone marrow-or bursa-derived cells) are the major cellular components of the adaptive immune response.

Detailed explanation-4: -B lymphocytes (B cells). These make antibodies that help your body fight infections. T lymphocytes (T cells). These attack foreign cells, cancer cells, and cells infected with a virus. Natural killer cells (NK cells). These contain substances that can kill tumor cells or cells infected with a virus.

Detailed explanation-5: -Effector Cells. Depending on the APC a naïve cell comes across it can become an effector T cell. Cytotoxic T Cells. Cytotoxic T Cells, also known as CD8+ cells, have the primary job to kill toxic/target cells. Helper T Cells. Regulatory T Cells. Memory T Cells. Applications.
