Yes. The first signal that a T cell receives from an antigen presenting cell (dendritic cell) is MHC presenting an antigen (foreign peptide). This gives the T cell specificity to this antigen.
The T cell enters a state of anergy. In this case, the T cell becomes tolerant to that antigen and is unable to divide or to secrete cytokines. This state of unresponsiveness to antigen is called anergy.

When a B cell recognizes an antigen, it will undergo activation and differentiation into plasma cells, which produce antibodies specific to that antigen. Some B cells may also differentiate into memory cells that provide long-lasting immunity to the antigen. This process is essential in the adaptive immune response to eliminate pathogens and prevent future infections.
The red blood cell antigen named after the rhesus monkey is the Rh factor or Rh antigen. It is an important antigen in blood transfusions and plays a role in hemolytic diseases of the newborn when an Rh-negative mother carries an Rh-positive fetus.
A non-self antigen is a 'Foreign' cell or chemical which is not naturally found inside the body.
Yes. The first signal that a T cell receives from an antigen presenting cell (dendritic cell) is MHC presenting an antigen (foreign peptide). This gives the T cell specificity to this antigen.

Yes that is true, and they only attach to a non-self antigen, that is, an antigen not produced in the body. and they only attach to certain antigens

This process is essential in the adaptive immune response to eliminate pathogens and prevent future infections.
An antigen can be anything from virus to bacteria to a soluble protein from outside or inside a cell. This includes both foreign and self peptides. An antibody that finds an appropriate antigen will bind to it and your B and T cells determine if it's self or not. A processed antigen came from cytosol. A protein will be taken by ubiquitin to a proteosome where it is broken up into small peptides. These peptides will make their way into the endoplasmic reticulum (through TAP) where they are exposed to MHC's.
