Question
Some T lymphocytes respond to antigen stimulation by synthesizing a growth factor that causes their own proliferation. This is an example of:
Explanation
Autocrine signalling, is consistent with established principles of cell signaling, receptor pharmacology and cellular regulation. Experimental measurements of binding parameters, genetic loss-of-function studies and pharmacological interventions all converge on the same interpretation. Related options address neighboring concepts but do not satisfy the precise criterion stated in the question.
