Virology Lectures 2026 #14: Adaptive defenses

The last line of defense is the adaptive immune system, which comprises T and B cells. Unlike intrinsic and innate defenses, it is tailored to the pathogen and features long term memory. In this lecture we examine how the innate immune system informs the adaptive system, how antibodies and cytotoxic T cells are made, their roles in preventing and resolving virus infections, and the establishment of immune memory.
