Astaxanthin is POSSIBLY SAFE when taken by mouth as a supplement. Astaxanthin has been used safely by itself in doses of 4 to 40 mg daily for up to 12 weeks. It has been used safely in combination with other carotenoids, vitamins and minerals at 4 mg daily for up to 12 months. Early research suggests that a combination product (BioAstin) containing astaxanthin, lutein, beta-carotene, and vitamin E taken by mouth 3 times daily for 8 weeks does not reduce pain in people with carpal tunnel syndrome.
Microglial cells are involved in protecting the brain and spinal cord from parasitic infections, as well. The phagocytosis of cerebral malaria and management of the damage caused by it is one example. Plasmodium falciparum is a parasite that causes malaria in humans.
Helper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. The T cell receptor is found on both CD4+ and CD8+ T cells.
