- Helper T cells, due to their role in immune system activation, are also unfortunately highly susceptible to HIV infection, leading to significant immunosuppression.
- Helper cells can activate and direct the activity of killer T cells, guiding them to the location of infected cells or pathogens for targeted elimination.
- Research on helper cells has led to significant advancements in the understanding and treatment of autoimmune disorders and other immunological diseases.
