The Role of Innate Immunity in Infectious Diseases

Infectious diseases continue to pose a global threat to human health, necessitating a thorough understanding of the body's defense mechanisms. Innate immunity, the first line of defense against pathogens, plays a crucial role in the early recognition and elimination of invading microorganisms. This manuscript explores the intricate and dynamic role of innate immunity in infectious diseases, delving into the mechanisms of pathogen recognition, the activation of innate immune responses, and the crosstalk with adaptive immunity. By comprehensively reviewing the current literature and integrating recent advancements, this manuscript aims to provide a comprehensive overview of the pivotal role innate immunity plays in safeguarding the host against diverse infectious agents.
