American Sign Language (ASL) is a natural language that serves as the predominant sign language of Deaf communities in the United States and most of anglophone Canada.
Adaptive immunity refers to antigen-specific immune response. The adaptive immune response is more complex than the innate. The antigen first must be processed and recognized. Once an antigen has been recognized, the adaptive immune system creates an army of immune cells specifically designed to attack that antigen.
This process of acquired immunity is the basis of vaccination. Like the innate system, the adaptive system includes both humoral immunity components and cell-mediated immunity components. Unlike the innate immune system, the adaptive immune system is highly specific to a specific pathogen.his process of acquired immunity is the basis of vaccination.
