Sapienic acid inhibits microbial growth in this organ, where it’s produced by Propionibacteria-mediated degradation of triglycerides. (15[2])Increased porphyrin production in this organ due to Vitamin B12 supplementation is associated (-5[1])with a condition sometimes treated with tetracyclines. (15[1])KOH (“k-o-h”) dissolves cells (-5[1])from this organ (-5[1])to yield a “spaghetti and meatballs” (15[1])appearance in a positive test for Malassezia. (15[1])Filaggrin (15[1])mutations make this organ more susceptible to colonization by (15[1])reducing the integrity of (*) corneocytes. (10[3])Comedones (10[4]-5[1])(“kah-muh-DOH-neez”) form (10[1])in this (-5[1])non-pancreatic (10[1])organ, whose (10[1])resident dendritic cells (-5[1])are Langerhans (10[2]-5[1])cells. (-5[8])Along (-5[1])with (-5[1])mucous (10[1]-5[2])membranes, (-5[1])Staph aureus naturally colonizes this organ, where it processes (-5[1])apocrine gland secretions and sebum. (-5[1])For 10 points, (10[1])name this organ (10[1])where microbes and hyperkeratinization cause acne. (10[6])■END■ (10[19]0[1])
