    Membrane-permeable CPP-MT and CPP-MT-AuNP inhibit acrosomal exocytosis in sperm. Notes: Human sperm were incubated for 1 hour at 37°C in HTF medium with increasing concentrations of recombinant CPP-MT unconjugated ( A ) or conjugated to AuNPs ( B ).

    Assessing MARCKS function on acrosomal exocytosis in non-permeabilized sperm. ( A ) Capacitated and non-permeabilized sperm were treated for 30 minutes at 37°C with increasing concentrations of a permeable tetramethylrhodamine-labeled MARCKS ED peptide (ED-TMR). Acrosomal exocytosis was then initiated by adding 10 µM calcium ionophore A23187 (circles), 200 nM PMA (squares) or 15 µM progesterone (triangles), and the incubation continued for 15 minutes. The percentage of reacted sperm was normalized as described in Materials and Methods . The data represent the means±SEM of at least three independent experiments. The asterisks indicate significant differences from similar conditions without ED-TMR (*, p

    Illustration of main pathways to skin response via mast cells based on results shown in Fig. 4 . Nonresponder dogs showed skin responses to HCO-60, histamine dihydrochloride, concanavalin A, and A23187 comparable to those of wild-type dogs but no response to compound 48/80; the dysfunctional route in NR dogs would be downstream of the GPCR.
