An antigen presenting cell (APC) presents to our immune system via a T-cell receptor.
85% of our immune system is located in our gut. With conditions such as leaky gut, food becomes an APC. Stress also immediately thins our gut lining. Molecular mimicry occurs as our memory cells confuse innocent bystanders (other foods or even our own tissues) as invading organisms and attack these as well.
After first identifying what our body sees as a threat and subsequently avoiding these triggers, we can intervene across this cascade, either by helping T-cell regulation, limiting pro-inflammatory cytokines, or balancing our bodies with the necessary anti-inflammatory molecules.
