For example, the mean values of LL37/ hCAP18 in 1 study were reported as 970 ng/mL in sera from patients with psoriasis and 741 ng/mL in normal sera (22), whereas another study reported LL37/ hCAP18 levels in seras from patients with psoriasis as 106.3 ng/mL compared with 3.8 ng/mL in sera from healthy controls (24). This evidence concerns the gene CAMP and psoriasis.
