Self and non-self antigens?

Hey guys, so i'm slightly confused  ??? How does the body distinguish between self and non-self antigens?

is it through self receptors/non-self receptors ? or MHC markers?

There are receptors that detect non-self molecules (B-cell receptors and T-cell receptors are their names). You don't need specific receptors for self. Self is simply the absence of detection, i.e. if it's self there will be no receptor to see it as dangerous.
