Does sarcoidosis activate diverse transcriptional programs in bronchoalveolar lavage cells?
BAL cells in sarcoidosis are characterized by enrichment of distinct transcriptional programs involved in immunity and proteasomal processes. Our findings add to the growing evidence implicating alveolar resident immune effector cells in the pathogenesis of sarcoidosis and identify specific pathways whose activation may modulate disease progression.
Few studies in the literature were interested in the evolution of the two forms of pemphigus. They showed that the two populations share the same clinical course; nevertheless they revealed the frequency of partial remission, failed treatment, relapses, necessity of high dose of corticosteroids, and difficulties of discontinuing treatment in PF. Our study, suggests that PF and PV may share the same clinical course.
