The Pattern Recognition Receptors on Cells of the Innate Immune

Multiple Choice

The pattern recognition receptors on cells of the innate immune system are genetically encoded, meaning that their sequences and specificities are determined prior to the development of the individual. In contrast, the antigen receptors of B and T lymphocytes arise from a random rearrangement process that occurs differently in each lymphocyte as it develops. One potential problem entailed by the random process that generates lymphocyte antigen receptors is the possibility that:

A) Some antigen receptors might recognize the individuals on cells or antigens
B) Many lymphocytes might generate antigen receptors that don't recognize anything
C) Many lymphocytes might generate antigen receptors that recognize multiple different pathogens
D) Some antigen receptors might recognize foreign tissues and lead to graft rejection during organ transplantation
E) Some lymphocytes might not generate functional antigen receptor proteins
