TASK DEFINITION: In this task, you are given a sentence. You are expected to recognize the name of gene or protein. Although there might be several correct answers, you need to write one of them.
PROBLEM:  Partial inhibition of p50 and p105 expression by NF - kappa B1 antisense oligonucleotides significantly reduced T - cell proliferation and CD25 / IL - 2R alpha cell surface expression .

SOLUTION: IL - 2R

PROBLEM:  In conclusion , we illustrate that CD45R0 signals control early cytokine receptor - associated signaling processes and mRNA and DNA synthesis in activated human lymphoblasts .

SOLUTION: cytokine receptor

PROBLEM:  Using electrophoretic mobility shift assays and Western and Northern blot analyses , we studied NF - kappa B1 gene expression during T - cell stimulation via CD2 + CD28 .

SOLUTION:
CD2 + CD28
