Quantification of the main immune subsets in the epidermis (LCs) and dermis (Mac, CD4, and CD8 T cells) after identification by a machine-learning approach applied to biopsy specimens from six different HDs (adults, male or female and from multiple ethnic groups), with comparison to HS and warts from two patients. Data are presented as individual values (min to max). Boxplots show the median with IQR. No statistical analysis was performed here.
