Which type of immunity is primarily mediated by T lymphocytes?

• A. Natural immunity
• B. Adaptive immunity
• C. Innate immunity
• D. Passive immunity

Answer: (B)

The type of immunity primarily mediated by T lymphocytes is adaptive immunity. This form of immunity develops over time and is characterized by the body's ability to recognize specific pathogens and remember them for more efficient response upon subsequent exposures. T lymphocytes, or T cells, play a crucial role in this process; they are responsible for cell-mediated immunity, which includes recognizing and destroying infected cells and helping to activate other immune cells. Adaptive immunity is distinct from other types of immunity in that it involves a more tailored response to specific antigens, as opposed to the generalized nature of innate immunity, which is the body's first line of defense through barriers like the skin and immune cells that respond to threats in a non-specific manner. Natural immunity refers to the immunity one is born with or inherits, while passive immunity involves the transfer of antibodies from one individual to another, such as from mother to child. Thus, T lymphocytes are a central component of adaptive immunity, allowing for a sophisticated and improved response to pathogens over time.
