T-cells are a critical component of the adaptive immune system, responsible for directly killing infected host cells, activating other immune cells, and regulating immune responses. Their function is crucial for targeting specific pathogens and maintaining immune system balance to prevent autoimmune diseases.

T-cell Function

T-cells are a type of lymphocyte that play a central role in cell-mediated immunity, identifying and destroying infected cells and coordinating the immune response. They originate in the bone marrow and mature in the thymus, differentiating into various subtypes with distinct functions in immune defense.

T-cells

The adaptive immune system is a specialized and highly specific defense mechanism that evolves to recognize and eliminate pathogens more efficiently upon repeated exposure. It relies on the activation and clonal expansion of lymphocytes, which include B cells and T cells, to produce targeted responses and immunological memory.

Adaptive Immune System

Infected host cells

Immune cells are the body's defense units that identify and neutralize pathogens like bacteria, viruses, and other harmful agents. They play a crucial role in maintaining health by distinguishing between self and non-self, thus preventing infections and diseases.

Immune Cells

Immune responses are the body's defense mechanisms against pathogens, involving both innate and adaptive systems to identify and eliminate foreign invaders. These responses are critical for maintaining health and involve a complex interplay of cells, proteins, and signaling pathways to ensure effective protection and memory against future infections.

Specific pathogens

Immune system balance

Autoimmune diseases occur when the immune system mistakenly attacks the body's own cells, leading to chronic inflammation and tissue damage. These diseases can affect almost any part of the body and are influenced by genetic, environmental, and hormonal factors.
