Practice: Why do some pathogens destroy the host organism’s C5a proteins?
Concept #1: Pathogens Avoid Encounter with Phagocytes
Practice: Why do some pathogens destroy the host organism’s C5a proteins?
Practice: What benefit do pathogenic bacteria obtain from secreting membrane-damaging toxins?
Concept #2: Pathogen Use Capsules & M Proteins to Avoid Opsonization
Practice: The C3b complement protein is incredibly important for opsonization of pathogenic material. How do some pathogens avoid opsonization by interfering with C3b?
Concept #3: Pathogens Use Fc Receptors to Prevent Opsonization
Practice: Certain pathogens have Fc receptors on their surface to avoid which immune responses to infection?
Practice: Why would some pathogens inhibit the functions of C3 convertase as a defense mechanism against the host’s immune cells?
Practice: Streptococcus pyogenes creates a C5a peptidase enzyme which breaks down the host’s C5a proteins. Breaking down the C5a proteins has what result?
