Figure 8From: Decreased Langerhans Cell Responses to IL-36γ: Altered Innate Immunity in Patients with Recurrent Respiratory PapillomatosisExpression of CCL1 in iLCs correlates with severity of RRP. The level of constitutive CCL1 expression in iLCs from patients with RRP was determined by q-PCR. Expression levels in iLCs from eight controls were defined as 100%; and individual samples clustered tightly around the 100% value (not shown); there was nearly a two-log reduction in expression as severity increased in the patients, p < 0.0001. Disease severity score is a composite value of the rate of regrowth of papilloma mass divided by the time in days since the previous surgery. A score over 0.06 is classified as severe disease.Back to article page
