how are the killer and regulatory cells
t helper cell bind to antigen presenting cell and become acitvated. once activatd, they rlease interleukins which stimulate the acivatiom of the t killer cells.
what do t regulatory cells do
supress the immune responce so that cell mediwted rsponce only occurs when pathogen is acivtated
what do t killer cells do
release oroteins, porforins to crewte hooes and enable cell desth
what is the himge rewson
allows flexibility so the antibody can bind to many pathogens
bioinformatics
stores large amount of data
eg dna and amino acid sequences
protein structyre
computational biology
needed for analysis of large amounts of data
eg preediction of amino acid sewunce
what are calcium ions needed for
increase permeability of the bacterial cell membrane making it easier for the plasmis containjng the bacteria to enter the bacterial cell
cell mediated
t helper cell bunds to apc
th cell release interleukins
stimulaarw divide by mitosis to create t memory and killer cells
what does hypothalamus sti,ukate in fight or flight
peptide horomone causing anterior pituituwry glamd to release ACTH causimg the adrenal cortex to release cortisol
what do baroreceptors detect
blood pressure
how does san rewpind when increwsing hewrt rate
increases the rate at which is generwtes excitwtions
what happmes when calcium ions bind to troponin
causes a confonical change in the shape of the troponin- tropomyosin co,plex
cebebellum
involved in muscular movement and coordination
