Hi,

I am struggling with the concept of B cells and T cells. I know that there are two types of B cells (plasma and memory) but I don't understand how they link with T cells? And also, what do each type of T cell do?

Are you doing A2 Edexcel Biology too. I've started immunity in class and don't understand it either, especially the T and B cell aspect. I am going over it this afternoon, if I understand it I will let you know! haha

Nope, I'm doing A2 Edexcel SNAB, I assume it's different to Edexcel Biology??

I think SNAB and Edexcel are the same, but I may be wrong!

Basically B cells release antibody necessary to target an "enemy" (called pathogen). (It is like producing GPS robot, that follow/attach to the enemy)

They start producing GPS robot when:

1-they touch an enemy and "call" other B cells to produce antibody
2-T cells with the "enemy intel" (e.g. T cell found car/address of the enemy) touch B cells and tell them to create these robots to trace enemy so the normal force (police=macrophages) and specialised T cell can kill them.

Some T cells can either
1-kill the "enemy" on sight
2-get the car/house address of the "enemy" and then tell B cell to use GPS robot to target them in the blood stream. (enemy Intel T cell)

There are more functions and mechanism, but I would struggle to explain them with such scenario.

I will try:
Suicide Macrophages = those who hide the enemy inside and let them grow the enemy organization. Usually, they let the enemy inside to kill, but sometimes those enemy are resistant to the weapon of the macrophages that usually kill the enemy. Hence, they decided to sacrifice themself and leak intel on their surface (intel is called MHC II), which is often recognized by T cells intel but also B cells. The required weapon is often created by B cells with assistant of specialised T cells and other cells (secret agent of different department of the immune: complement system and agglutinaiton process players).

Hope it makes it a bit clear ...

It does, Thank you very much!! I now understand the basics from this video - which is good! https://www.youtube.com/watch?v=l4S1YN2GWHE
