Abstract
Background: MICA and MICB are tightly regulated stress-induced proteins that trigger the immune system by binding to the activating receptor NKG2D on cytotoxic lymphocytes. MICA and MICB are highly polymorphic molecules with prevalent expression on several types of solid tumors and limited expression in normal/healthy tissues, making them attractive targets for therapeutic intervention. Methods: We have generated a series of anti-MICA and MICB cross-reactive antibodies with the unique feature of binding to the most prevalent isoforms of both these molecules. Results: The anti-MICA and MICB antibody MICAB1, a human IgG1 Fc-engineered monoclonal antibody (mAb), displayed potent antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP) of MICA/B-expressing tumor cells in vitro. However, it showed insufficient efficiency against solid tumors in vivo, which prompted the development of antibody-drug conjugates (ADC). Indeed, optimal tumor control was achieved with MICAB1-ADC format in several solid tumor models, including patient-derived xenografts (PDX) and carcinogen-induced tumors in immunocompetent MICAgen transgenic mice. Conclusions: These data indicate that MICA and MICB are promising targets for cytotoxic immunotherapy.

Abstract
B cells play a major role in the pathogenesis of many autoimmune disorders, including rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, and type I diabetes mellitus, as indicated by the efficacy of B cell-targeted therapies in these diseases. Therapeutic effects of the most commonly used B cell-targeted therapy, anti-CD20 mAb, are contingent upon long-term depletion of peripheral B cells. In this article, we describe an alternative approach involving the targeting of CD79, the transducer subunit of the B cell AgR. Unlike anti-CD20 mAbs, the protective effects of CD79-targeted mAbs do not require cell depletion; rather, they act by inducing an anergic-like state. Thus, we describe a novel B cell-targeted approach predicated on the induction of B cell anergy.

Abstract
OBJECTIVE The S100A9 and S100A8 proteins are highly expressed by neutrophils and monocytes and are part of a group of damage-associated molecular pattern molecules that trigger inflammatory responses. Sera and synovial fluids of patients with rheumatoid arthritis (RA) contain high concentrations of S100A8/A9 that correlate with disease activity. METHODS In this study, we investigated the importance of S100A9 in RA by using neutralizing antibodies in a murine lipopolysaccharide-synchronized collagen-induced arthritis model. We also used an in vitro model of stimulation of human immune cells to decipher the role played by S100A9 in leukocyte migration and pro-inflammatory cytokine secretion. RESULTS Treatment with anti-S100A9 antibodies improved the clinical score by 50%, diminished immune cell infiltration, reduced inflammatory cytokines, both in serum and in the joints, and preserved bone/collagen integrity. Stimulation of neutrophils with S100A9 protein led to the enhancement of neutrophil transendothelial migration. S100A9 protein also induced the secretion by monocytes of proinflammatory cytokines like TNFα, IL-1β and IL-6, and of chemokines like MIP-1α and MCP-1. CONCLUSION The effects of anti-S100A9 treatment are likely direct consequences of inhibiting the S100A9-mediated promotion of neutrophil transmigration and secretion of pro-inflammatory cytokines from monocytes. Collectively, our results show that treatment with anti-S100A9 may inhibit amplification of the immune response and help preserve tissue integrity. Therefore, S100A9 is a promising potential therapeutic target for inflammatory diseases like rheumatoid arthritis for which alternative therapeutic strategies are needed.

Abstract
The MHC class-I related receptor or neonatal Fc receptor (FcRn) protects IgG and albumin from degradation by rescuing them in endothelial cells in a pH dependent fashion and consequently increases their respective half-lives. Monoclonal antibody-based therapies are of increasing interest and characterizing the interaction with FcRn is important for the development of an antibody candidate. In order to facilitate the production of soluble FcRn suitable for interaction studies, we generated semi-stable pools co-expressing FcRn α-chain, β2-microglobulin, biotin ligase and EGFP using a dual promoter, multi-cistronic vector. Human and mouse FcRn were purified in the mg/L range of culture medium and a single purification step was sufficient to reach a high level of purity. The receptors were characterized by ELISA, flow cytometry and surface plasmon resonance and shown to be functional. The single site biotinylation facilitated the directional immobilization of FcRn on the sensor chip and significantly increased the response level of the surface compared to amine coupling used in previous studies. Using this system, the affinity constants of seven IgGs, from various species and isotypes, were determined for human and mouse FcRn, including two hamster isotypes. These results confirm the higher selectivity of the human receptor and the promiscuous binding of mFcRn to IgGs from different species.

Abstract
Neutrophil migration from the blood to inflammatory sites follows a cascade of events, in which adhesion to endothelial cells and extracellular matrix proteins is essential. S100A8, S100A9, and S100A12 are small abundant proteins found in human neutrophil cytosol and presumed to be involved in leukocyte migration. Here we investigated the S100 proteins' activities in neutrophil tissue migration by evaluating their effects on neutrophil adhesion to certain extracellular matrix proteins. S100A9 induced adhesion only to fibronectin and was the only S100 protein that stimulated neutrophil adhesion to this extracellular matrix protein. Experiments with blocking antibodies revealed that neither beta1 nor beta3 integrins were strongly involved in neutrophil adhesion to fibronectin, contrary to what the literature predicted. In contrast, neutrophil adhesion to fibronectin was completely inhibited by anti-beta2 integrins, suggesting that S100A9-induced specific activation of beta2 integrin is essential to neutrophil adhesion.
