Immune evasion is a research area that focuses on how pathogens, tumors, or other entities can evade or suppress the immune system to avoid detection and destruction. This can include mechanisms such as hiding from the immune system, inhibiting immune responses, or promoting immune tolerance. Understanding immune evasion is critical for developing effective treatments and therapies for diseases such as cancer, autoimmune disorders, and infectious diseases. Research in this area often involves studying the interactions between the immune system and pathogens or tumors, as well as identifying strategies to enhance immune responses and overcome immune evasion mechanisms.
