TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['The aim of this study was to investigate effects of CD137 ligand (CD137L)-mediated reverse signaling on cellular responses in thioglycollate-elicited mouse peritoneal macrophages.', 'Five-week-old male C57B6 mice were injected intraperitoneally with thioglycollate for 3 days to isolate peritoneal macrophages. We counted total cell numbers with a Cell Lab Quanta SC. CD137L expression was examined with a flow cytometer. We also measured expression of inflammatory cytokines by flow cytometry and/or real time-PCR.', 'Cross-linking of CD137L with recombinant CD137-Fc protein (rCD137-Fc) increased total numbers of thioglycollate-elicited mouse peritoneal macrophages (hIgG-Fc- vs. rCD137-Fc-treated group, p < 0.05). However, ligation reduced the increase in IL-1β and IL-6 levels. Real-time PCR analysis showed that treatment of cells with rCD137-Fc also reduced transcript levels of IL-1β, IL-6, iNOS and COX2 (hIgG-Fc- vs. rCD137-Fc-treated group, p < 0.05), as well as expression of CD137L.'] Does cross-linking of CD137 ligand modulate immune responses of thioglycollate-elicited mouse peritoneal macrophages?
OUTPUT:
