uh no thats got nothing to do with their function. u just had to say one makes plasma cells which secrete antibodies that attack antigens and t-cells have killer t cells which directly attack antigens

 

[HeyKrazi]

hmmmmm
i talked bout b cells = antibody mediated response - antibodies are produced to attack antigens; t cells = cell mediated response - t cells coordinate themselves and other lymphocytes to attack the pathogen

i thought it should have had more lines than it did. there was no way you could distinguish between them properly in 3 lines

oh i loved this question...

in a huge summary
B-cell produce antibodies
T-cells control other lymphocytes by succreating lymphokines to make b-cells produce antibodies, bind with a specific antigen on the protein coat of a macrohpage. Killer T, suppressor T and helper-T functions

 

[Dokoism]

I also said that t-helper cells promote the production of more b+t cells to fight infection (something like that? :S) and also end the immune response with suppressor t-cells

 

[Jessisbored]

yep it does that too. i said that also

 

[hiphophorray123]

b cells do not circulate (their lazy) but they are stimulated when antigens make it past the 1st line of defence, this is when b cells strat producing plasma, the plasma produces antibodies which deal with the antigens

T cells circulate (their active) and they deal with antigens more directly particularly with t killer cells.

thats all u had to say

 

[myg0t]

Also not a bad idea to mention they work together. I think i stooged this question coz i said that B cells produce antibodies, T cells may do same or kill antigen directly. beh

answer

I put that b cells are prodominantly memory cells an t cells are the doers, the attackers would this be a bit right???

 

[hiphophorray123]

^ no not for b cells....theres also T-memory cells so both do their part in memory

b cells main role is producing plasma, which produces antibodies

 

[Misturi]

I did what jess did, l put the types of t cells in brackets and just said everything else she said!
