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.

Input: Consider Input:  Notably , CD28 ligation activated p38 MAPK and CaMKIV , the kinases stimulated by CD3 engagement , suggesting that CD28 acts by increasing the activation extent of p38 MAPK and CaMKIV .

Output: p38 MAPK


Input: Consider Input:  Although the VP16 369 - 380 peptide has a lower binding affinity for DQ0602 molecules than the VP16 33 - 52 peptide , T cells that recognized the VP16 369 - 380 peptide occurred at a much higher frequency than those that were specific for the VP16 33 - 52 peptide .

Output: DQ0602 molecules


Input: Consider Input:  Binding of human immunodeficiency virus type 1 to CD4 and CXCR4 receptors differentially regulates expression of inflammatory genes and activates the MEK / ERK signaling pathway .


Output: inflammatory genes
