This study delves into the effects of crosslinked dacetuzumab on cell death (apoptotic and necrotic) and proliferation in Ramos cells. The research explores the signaling cascades involving phospho-ERK1/2, phospho-p38 MAPK, IkB-a, and phospho-AKT. The experiment also examines CD40 Ligand and hIgG interactions with dacetuzumab to uncover potential mechanisms underlying cellular responses. Findings are presented in Supplementary Figure 1 by Lewis et al.
