5 Questions
Which statement accurately describes the role of antibodies in defense against bacteria with polysaccharide-rich capsules?
Antibodies bind to capsular polysaccharides, promoting phagocytosis and bacterial destruction.
What is the main function of T-independent antibody responses in infants and young children?
Providing weak defense against bacteria with capsules.
What distinguishes tissue-resident memory cells from other subsets of Memory T cells?
They reside in skin and mucosal tissues, unable to enter circulation.
Which statement accurately describes the longevity of Memory T cells?
Memory T cells survive long after infection and antigen clearance.
Which statement accurately describes the function of complement protein C3d?
C3d enhances antigen-dependent responses by promoting tyrosine phosphorylation of ITAMS.
Learn about the immune response against bacterial capsule polysaccharides, how antibodies target bacteria for destruction, and the role of T-independent antibody responses. This quiz covers the defense mechanisms against bacteria with polysaccharide-rich capsules.
