Is interleukin 12 expressed and actively released by Crohn 's disease intestinal lamina propria mononuclear cells?
IL-12 transcripts are expressed in CD intestinal tissues. CD LPMCs are up-regulated in their capability of releasing bioactive IL-12. Expression and release of bioactive IL-12 seem to differentiate CD from UC.
A significant enhancement of intraocular transgene expression is associated with periocular pretreatment with corticosteroid. Histologic evidence of immune cell reduction in ocular tissues in corticosteroid-treated eyes implies a local immune response. Periocular treatment with corticosteroids may enhance adenovirus-mediated gene expression in the eye.
