Deciphering the Oncogenic Lesions and Pathways of B and T Cell Cancers

Human Antibody Responses to Viruses Adaptive immune responses naturally occurring upon infection or induced by vaccination generate high affinity antibodies, and memory B-cell subsets to respond to further antigenic challenges, providing protection against (re-)infections. […]
