Are Cytoxic T cells able to proliferate into plasma cells and memory cells?

I know B cells form plasma cells and memory cells. And i think I read somewhere that Tc cells maybe able to form memory cells.

But now i found that Tc cells also proliferate into plasma cells and memory. 😕

I never heard of cytotoxic T cells proliferating into plasma cells. T cells can proliferate into memory cells but cytotoxic T cells cannot.

You're pretty much confusing all of these with each other. There are two types of immune response:

1-Cell Mediate Immune Response:
*************************
This is mainly controlled by two types of cells:
a)Killer T-cells>>These are cytotoxic cells that recognize invaders and puncture their membrane in order to kill them.
b)Helpter T-cells>>These are T-cells that recognize invaders and amplify both the cell mediate immune response and humoral response via production of Interleukins upon detection of invaders. They amplify this by recruiting more B-cells and Killer T-cells to the invasion site. Furthermore, interluekins tend to trigger the proliferation of Killer T-cells and B-cells.

2-Humoral Immune Response:
**********************
This is mainly controlled by two types of cells:
a)Plasma B-cells>>Cells that release their antibodies into the bloodstream. The antibodies are only effective as long as they remain in circulation. Eventually the body will remove these antibodies-->The effect is short lived.
b)Memory B-cells>>Unlike Plasma B-cells, these don't release their antibodies into the bloodstream. Therefore, they remain within the body for a longer period of time, allowing the body to immediately "remember" the same invaders, next time they attack the body, and destroyer them.

That is a really helpful breakdown. But actually I am aware of all this. In addition to this I read at one place (could be kaplan flash cards) that Tc cells can also have memory. And now i read Tc cells can proliferate into plasma cells. I highly doubt it because most books say only b cells become plasma cells. So I just wanted to confirm if anyone else know of this "special" quality of Tc cells 🙂

but thanks for the breakdown anyways. 👍
