Key Concepts

Dendritic Cells

Dendritic cells serve as key antigen-presenting cells that capture, process, and present antigens to T cells. They act as a bridge between the innate and adaptive immune systems by initiating and shaping the T cell responses against pathogens.

Natural Killer (NK) Cells

Natural Killer cells are a subset of lymphocytes that provide a rapid response to infected or transformed cells. They can identify and eliminate cells that display abnormal or absent major histocompatibility complex (MHC) markers without prior sensitization.

Mast Cells

Mast cells are a type of immune cell primarily involved in initiating inflammatory responses and mediating allergic reactions. They release histamine and other inflammatory mediators when activated, playing a crucial role in the early stages of the immune response.

Eosinophils

Eosinophils are granulocytic white blood cells that participate in the defense against parasitic infections and are also involved in modulating allergic responses. Their granular contents can damage and neutralize invading parasites and contribute to tissue inflammation.

Helper T Cells

Helper T cells are pivotal components of the adaptive immune system that coordinate the immune response. They activate and regulate the functions of other immune cells, including cytotoxic T cells, B cells, and macrophages, thereby orchestrating an effective defense against pathogens.
