"Manual" enrichment analysis of gene set for genes associated with cell types

Question

[rebeliscu]

Using WGCNA, I have a set of gene modules; these modules have correlations associated with a treatment.

I want to test whether certain modules can be characterized as representing a certain cell-type (e.g. astrocytes) by using established cell-type marker genes.

I'm not quite sure how to go about this. If anyone could point me in the right direction as to how to enact this workflow, I would be very grateful!

Thanks in advance.
