A. Hmmm… not totally sure here. Great question though! My limited understanding is that there is a surface receptor type recognition system used by the “defensive” cells of the 2nd line of defence in detecting pathogens in general BUT it would not be referred to as antigen recognition. Remember, antigens are substances that result in antibodies being produced and this is limited to the specific immune response. This level of detail should not be asked by VCAA.
