[answerhappygod]

For each of the described phagocytosis events by the
following Antigen Presenting Cells, what will the “sticking” T
cells do? Activate? Undergo permanent shut off?
Antigen Presenting Cell phagocytosis Scoparia pollen
segment along with E. Coli bacteria
Vaccine delivers influenza segments (not PAMP molecules)
tethered to PAMP molecules that came from Streptococcus pyogenes
bacteria (causes Strep throat)
Vaccine delivers banana proteins along with Influenza
PAMP molecules
The host is exposed to yellow fever
Do many of us have adaptive cells that have antigen
receptors that recognize (are sticky to) cocaine
molecules?
Designing vaccines to elicit drugs?
Could we somehow create a vaccine to have the immune
system target and attack cocaine molecules once they are present in
us?
Designing vaccines to melanoma cancer?
Could we somehow create a vaccine to have the immune
system target and attack molecules only found on cancer cells like
melanoma?
What challenges might you face with attempting to elicit
an effective immune response to the melanoma cancer?
