Key Concepts

Natural Killer Cell

Natural killer cells are lymphocytes that play a critical role in the innate immune system. They detect and destroy virus-infected cells and tumor cells by releasing cytotoxic molecules such as perforin and granzymes, which induce apoptosis without the need for prior sensitization or antigen specificity.

Basophil

Basophils are a type of granulocyte known for their large cytoplasmic granules containing histamine and other mediators. They stain with basic dyes and are prominently involved in allergic reactions and inflammatory responses as well as in defense against parasites.

Macrophage

Macrophages are large, phagocytic cells derived from monocytes, classified as part of the innate immune system. They reside in tissues where they engulf pathogens, clear cellular debris, and can present antigens to activate the adaptive immune response.

Eosinophil

Eosinophils are granulocytes characterized by their staining with acidic dyes due to the presence of granules rich in proteins like major basic protein. They are particularly important in combating parasitic infections and modulating allergic inflammatory responses.
