What happens when B cells bind antigens? Describe the steps involved and the outcomes.

B cell receptor signaling include the  following EXCEPT

T cells expressing y:d T-cell receptors have been found to recognize a diversity of ligands, including pathogen-derived proteins, self-peptides, and stress-induced molecules.

Second messengers, such as calcium ions (Ca2+), are chemical mediators commonly used in intracellular signaling pathways

BCR stimulation and TCR stimulation generally activate similar downstream signaling modules, but do so using related, but not identical, signaling proteins. From the list below, match each B cell protein to its T cell counterpart.

B cell development in the bone marrow is an inherently wasteful process. Nearly half of the pro-B cells produced will die without progressing to the next stage of development. This massive loss of pro-B cells is due to

Repartimiento labor was based on 

In colonial Latin America, the term encomienda referred to

After slavery was outlawed in Latin America, free immigrants continued to arrive from various regions of the world.  Which of the following was one of these regions?
