Abstract
The presence of cytokines in the peripheral nerve was positively correlated to the induction and progression of inflammation during experimental allergic neuritis (EAN) and Guillain Barré syndrome (GBS). We investigated the induction of adhesion molecules such as L-selectin, E-selectin, ICAM-1, VCAM-1 and Mac-1 on Schwann cells by proinflammatory cytokines. Cultured human Schwann cells from normal adult, fetal and diabetic nerves were studied by immunofluorescence at basal condition and after stimulation with cytokines for 6, 24, 48 and 96 h. Incubation of human Schwann cells with TNFalpha, IFNgamma and IL-1beta induces the expression of ICAM-1 starting at 6 h and reaching a peak at 24 h on more than 90% of cells. VCAM-1 expression was induced after 6 h of treatment with TNFalpha and IL-1beta on almost 100% of Schwann cells. Surprisingly, stimulation with TNFalpha, IFNgamma and IL-1beta also induced the expression of L-selectin on fetal and diabetic Schwann cells, but not on normal adult cells. E-selectin, an adhesion molecule classically upregulated during inflammation, as well as Mac-1, a ligand for ICAM-1, were not expressed on human Schwann cells at basal condition or after treatment with cytokines. No ICAM-1, VCAM-1 and L-selectin expression was found on unstimulated Schwann cells. Our results suggest that upregulation of adhesion molecules on Schwann cells may have a role in the pathogenesis of inflammation in the peripheral nerve.

Abstract
Non-classical antigen-presentation by CD1 molecules expressed on cytokine-activated monocytes (CAM), and cell-mediated responses supported by double-negative (DN) and by CD8+ responder alphabeta T cells, are involved in host resistance against mycobacterial infections. The CD1b protein is responsible for presentation of non-peptide, lipid antigens to T cells. In this context, a pivotal role is played by induction of CD1b protein on the membrane of human monocytes activated by GM-CSF alone, and more efficiently by GM-CSF combined with IL-4. Rifampin (RFP), a drug which is extensively utilized for chemoprophylaxis or treatment of Mycobacterium tuberculosis, is known to reduce a number of B, or T cell-dependent responses. Therefore we undertook immunopharmacological studies on RFP, to determine the effects of this agent on human macrophage function, relative to antigen presentation by CD1b molecules and on DN T cell cytolytic function. The results showed that: (a) graded concentration of RFP (2 or 10 microg/ml) induced a significant increase of CD1b expression, in CAM as evaluated by FACS analysis; (b) RFP increased significantly the specific mAb binding to CD1b on CAM surface; (c) treatment of effector cells with RFP did not reduce DN T cell-mediated cytolysis against lymphoblastoid cells transfected with CD1b cDNA (C1R.b6 cells), pulsed with M. tuberculosis. These results suggest that RFP could be of potential value in improving mycobacterial antigen presentation without impairing responder T cell function.

Abstract
Strong immunogenicity is induced by antitumor triazene compounds in tumor cells through a mutagenic mechanism. A highly immunogenic <<D>> clone, isolated from a dacarbazine-treated L5178Y leukemia of DBA/2 mice, was transfected with K-ras mutated at codon 12 (i.e. ras(m12)). This transfected clone presents at least 2 mutations, one concerning K-ras gene, and the other affecting an unrelated gene, responsible for the generation of a highly immunogenic, MHC class I restricted non-self peptide. The results indicate that cells of <<D>> clone transfected with ras(m12) were less immunogenic than cells of the same origin transfected with the vector alone. Moreover, ras(m12)-transfected cells showed lower levels of H-2K(d) gene expression with respect to those detectable in control cells. In addition, in vivo and in vitro sensitization against <<D>> clone carrying mutated ras did not result in a strong cytotoxic T lymphocyte response against ras(m12)-transfected non immunogenic L5178y target cells. These preliminary results suggest that K-ras mutation could down-regulate the level of tumor immunogenicity, possibly acquired through a mutagenic process affecting other unrelated genes.
