In this study, we show that engagement of CTLA-4 on tumor-infiltrating lymphocytes from low-dose melphalan (L-phenylalanine mustard (L-PAM))-treated MOPC-315 tumor bearers led to IL-10 secretion. In addition, the inhibitory activity of CTLA-4 ligation for IFN-gamma secretion following stimulation with anti-CD3 plus anti-CD28 mAb depended on IL-10 production. Consistent with the importance of IL...

Inflammation and oxidative stress play fundamental roles in the pathogenesis of atherosclerosis. Myeloperoxidase has been extensively implicated as a key mediator of inflammatory and redox-dependent processes in atherosclerosis. However, the effect of synthetic myeloperoxidase inhibitors on atherosclerosis has been insufficiently studied. In this study, ApoE(-/-) mice were randomized to low- an...

Antiidiotypic antibody (AIA) was raised in mice by immuni zation with MOPC 315 immunoglobulin A emulsified in Freund's adjuvant (FA). The antibody content of mouse serum was assessed by (a) its ability to inhibit resetting of 2,4,6-trinitrophenyl-sheep red blood cells around MOPC 315 myeloma cells, and (b) by a solid phase antigen-binding plate assay based on reactivity with 125l-Protein A and ...

The prevalence of mutations at amino acid (aa) position 315 in the katG gene of isoniazid (INH)-resistant Mycobacterium tuberculosis isolates in The Netherlands and the mutation's association with the level of INH resistance, multidrug resistance, and transmission were determined. Of 4288 M. tuberculosis isolates with available laboratory results, 295 (7%) exhibited INH resistance. Of 148 aa 31...

Abstract Background Previous studies have shown significant differences and lack clarity on whether resistance to either isoniazid or rifampicin can predict multidrug tuberculosis (MDR-TB). Some consider be a surrogate for MDR-TB. We, therefore, conducted this study determine Results A total of 315 Mycobacteria isolates were tested against isoniazid, rifampicin, ethambutol streptomycin using th...
