Generation and characterization of small single domain antibodies inhibiting human tumor necrosis factor receptor 1.
The cytokine TNF is a well known drug target for several inflammatory diseases such as Crohn disease. Despite the great success of TNF blockers, therapy could be improved because of high costs and side effects. Selective inhibition of TNF receptor (TNFR) 1 signaling holds the potential to greatly reduce the pro-inflammatory activity of TNF, thereby preserving the advantageous immunomodulatory signals mediated by TNFR2. We generated a selective human TNFR1 inhibitor based on Nanobody (Nb) technology. Two anti-human TNFR1 Nbs were linked with an anti-albumin Nb to generate Nb Alb-70-96 named "TNF Receptor-One Silencer" (TROS). TROS selectively binds and inhibits TNF/TNFR1 and lymphotoxin-α/TNFR1 signaling with good affinity and IC50 values, both of which are in the nanomolar range. Surface plasmon resonance analysis reveals that TROS competes with TNF for binding to human TNFR1. In HEK293T cells, TROS strongly reduces TNF-induced gene expression, like IL8 and TNF, in a dose-dependent manner; and in ex vivo cultured colon biopsies of CD patients, TROS inhibits inflammation. Finally, in liver chimeric humanized mice, TROS antagonizes inflammation in a model of acute TNF-induced liver inflammation, reflected in reduced human IL8 expression in liver and reduced IL6 levels in serum. These results demonstrate the considerable potential of TROS and justify the evaluation of TROS in relevant disease animal models of both acute and chronic inflammation and eventually in patients.Sophie Steeland, Leen Puimège, Roosmarijn E Vandenbroucke, Filip Van Hauwermeiren, Jurgen Haustraete, Nick Devoogdt, Paco Hulpiau, Geert Leroux-Roels, Debby Laukens, Philip Meuleman, Martine De Vos, Claude Libert

[Analysis of coagulation factor XIII in Crohn's disease--establishment of a novel monoclonal anti-coagulation factor XIII antibody].
A novel monoclonal anti-human coagulation factor XIII (F. XIII) antibody (2C3 antibody) raised in BALB/c mice was established by Kohler and Milstein methods. The monoclonal antibody recognized F. XIII of 85 KD demonstrated by western blotting analysis. Plasma F. XIII-IR levels measured by ELISA with 2C3 antibody were significantly lower in active disease than in quiescent disease in a total of 21 Crohn's disease (CD) patients. Plasma F. XIII levels were significantly lower on admission in CD with fistulas than in CD without fistulas. Relationships between activities of CD and plasma F. XIII levels were shown. No significant relationships, however, were observed between F. XIII-IR levels and nutritional states assessed by TP, ALB, TF, PA, RBP, %IBW. Low levels of F. XIII in active CD patients with fistulas may occur regardless of hyponutrition. By using 2C3 antibody, global functions of F. XIII will become clarified as well as pathologic and diagnostic roles of plasma F. XIII in CD.T Ayabe, T Ashida, M Taruishi, Y Saito, M Murakami, T Obara, Y Shibata, M Namiki
