[Leukocyte migration inhibition factor in acne vulgaris]

The inhibition factor of the leucocytic migration was studied in 26 patients with Acne Vulgaris, stages III and IV, being positive in all the cases. The LIF positive shows the mobilisation of lymphocytic population, answering an active and constant immunologic conflict. As the PA is antigenic, because it produces a blastification (TTL positive), we can say that it acts as antigen provoking immunologic mechanisms which help to explain the inflammatory processes at the pilo-sebaceous follicle in the AV.
