Deep Dive: Innate Immune Responses
Master the fundamentals
Definition
Innate immune responses involve natural killer cells targeting infections and tumors, inflammation causing hot, swollen areas to fight irritants, and fever as a systemic response to pathogens. Fever creates an inhospitable environment for pathogens to slow their growth. Asymptomatic infections, where pathogens multiply without causing symptoms, highlight the body's silent defense mechanisms.
