This result is constant with our inability to discern variations in classic Mactivation markers in between controls and SScPF and inflammatory skin and suggests that classically activated M usually are not the source in the reported IFN signature we uncover.

However, CL genes’ expression is just not unique between disease and controls in either skin or lung (Wilcoxon p . and respectively; Fig. b). This result is constant with our inability to discern variations in classic Mactivation markers amongst controls and SScPF and inflammatory skin and suggests that classically activated M will not be the supply in the reported IFN signature we discover. Modules ALT and ALT are both associated with IL and IL therapy, which are stimuli connected with option activation of M . These two gene sets are nonoverlapping coexpression modules and thus represe.
