Question

What is the main function of Bcl-xL in the centrocyte?

a. Provide apoptotic signals.
b. Induce somatic hypermutation.
c. Upregulate the expression of activation-induced cytidine deaminase.
d. Prevent cell death.
e. Induce isotype switching.

Answer 1

The main function of Bcl-xL in the centrocyte is to prevent cell death by inhibiting the release of cytochrome C from mitochondria.

Step-by-step explanation:

The main function of Bcl-xL in the centrocyte is to prevent cell death.

Bcl-xL is a protein that belongs to the Bcl-2 family, which regulates apoptosis, or programmed cell death.

It acts by inhibiting the release of cytochrome C from mitochondria, which prevents the activation of caspases and subsequent cell death.

By preventing cell death, Bcl-xL helps maintain the survival and integrity of centrocytes.
