A major difference between Salmonella enterica and Shigella infections is that only in salmonellosis can: A. animals serve as a reservoir of infection B. diarrhea become the major symptom C. endotoxin play a ...

Immunology Exam 4 - Questions and Answers Treg cells that express FoxP3 are generally thought to have T-cell receptors that recognize self-peptides bound to MHC class II molecules. In the skin, keratin and filaggrin are among the self-antigens expressed. FoxP3+ Treg cells found in skin and skin-draining lymph nodes might be specific for the self-antigen, filaggrin. These FoxP3+ filaggrin-specific Treg cells: A. Would inhibit the activation of naive filaggrin-specific and keratin-specific CD4 T ...
