What are the Challenges in Overcoming Immune Rejection?
Despite advances, several challenges remain:
Diversity of the Immune System: The immune system is highly adaptable and can recognize a wide variety of foreign entities. This makes it difficult to design nanoparticles that can universally evade immune detection. Individual Variability: Different individuals have varying immune responses, making it challenging to develop one-size-fits-all solutions. Long-term Effects: The long-term effects of repeated exposure to nanoparticles are not fully understood, and there may be cumulative effects on the immune system.
