IL17A and Autoimmunity: Finally, we explore potential therapeutic strategies aimed at modulating memory cells to prevent or treat autoimmune disorders, including B cell-depleting therapies (e.g., Rituximab), T cell-targeting agents (e.g., Abatacept), and cytokine inhibitors (e.g., IL-17 or IL-23 blockers) that are currently used in diseases such as rheumatoid arthritis, multiple sclerosis, and psoriasis.
