12 Questions
What ensures specificity in adaptive immunity?
The staggering number of lymphocytes, each possessing specificity for only one antigen
What is the function of T cell receptor (TCR) in response to antigen?
Help other cells
What is the role of B cell receptor (BCR) in recognizing antigens?
Secrete antibodies
What property ensures diversity in adaptive immunity?
The staggering number of lymphocytes, each possessing specificity for only one antigen
Which type of receptors are TLRs (Toll-like receptors)?
Both cell membrane and endosomal receptors
What do NLRs (Nod-like receptors) recognize?
Damage-Associated Molecular Patterns (DAMPs)
What do PRRs bind to?
Unique microbial structures
What mediates cognitive functions in adaptive immunity?
Cell surface receptors
How does innate recognition of antigen differ from adaptive recognition?
Innate recognition is non-specific, while adaptive recognition is specific to particular antigens
Which term refers to the immunity resulting from the production of antibodies by the immune system in response to the presence of an antigen?
Active immunity
What is the role of apoptosis in immunity?
Regulating the proliferation and elimination of immune cells
What is the primary mechanism by which Fas/FasL interactions induce apoptosis in immune cells?
Triggering a signaling cascade that results in cell death
This quiz covers the cognitive phase in adaptive immunity, focusing on the specificity and diversity ensured by lymphocytes. It also discusses the recognition processes of B cell receptors (BCR) and T cell receptors (TCR).
