CD8+ T Cells. Recall that the T cell receptors on T cells with the CD8 molecule recognize antigen displayed on MHC I molecules. Thus, the role of CD8+ T cells is to identify cells that are synthesizing protein that is not a normal part of the body. This, of course, is what happens in a virally infected cell.oreover, T cell receptors always recognize peptide antigens presented on MHC molecules on the surface of other cells. Despite these common features, T cells perform several, quite different functions in the body. They are first divided into two populations based on whether they have CD4 molecules or CD8 molecules.
Pour 3 cans of beer or 36 oz. of water into a large soup pot. Add one sliced onion and four chopped garlic cloves. Bring the mixture to a boil and add 1 lb. of bratwurst that have been pierced with a fork to prevent splitting. When the mixture comes back to a boil, reduce the heat to low. Allow the bratwursts to simmer for 20 minutes. Drain them before cooking using your preferred method.
We use the term âboilâ here but itâs important to note the difference between boiling and simmering. A great basic bratwurst recipe such as our How to Cook Brats in BeerÃ¢ guide provides more details but here are the basics, as far as how long to boil brats. Youâll add your brats to a pot or large skillet and add equal parts liquid â either water and beer or just water â until the brats are covered by liquid.
