Th17

Th17 cells are a type of immune cell that play a key role in protecting the body against certain infections, especially bacteria and fungi. They help activate other parts of the immune system and promote inflammation to fight off pathogens. However, when Th17 cells become overactive or misdirected, they can contribute to autoimmune diseases like rheumatoid arthritis or psoriasis, where the immune system mistakenly attacks the body's own tissues. In summary, Th17 cells are essential defenders in your immune system, but balancing their activity is crucial for health.
