    Abstract Conventionally, hyperimmune globulin drugs manufactured from pooled immunoglobulins from vaccinated or convalescent donors have been used in treating infections where no treatment is available. This is especially important where multi-epitope neutralization is required to prevent the development of immune-evading viral mutants that can emerge upon treatment with monoclonal antibodies. Using microfluidics, flow sorting, and a targeted integration cell line, a first-in-class recombinant hyperimmune globulin therapeutic against SARS-CoV-2 (GIGA-2050) was generated. Using processes similar to conventional monoclonal antibody manufacturing, GIGA-2050, comprising 12,500 antibodies, was scaled-up for clinical manufacturing and multiple development/tox lots were assessed for consistency. Antibody sequence diversity, cell growth, productivity, and product quality were assessed across different manufacturing sites and production scales. GIGA-2050 was purified and tested for good laboratory procedures (GLP) toxicology, pharmacokinetics, and in vivo efficacy against natural SARS-CoV-2 infection in mice. The GIGA-2050 master cell bank was highly stable, producing material at consistent yield and product quality up to >70 generations. Good manufacturing practices (GMP) and development batches of GIGA-2050 showed consistent product quality, impurity clearance, potency, and protection in an in vivo efficacy model. Nonhuman primate toxicology and pharmacokinetics studies suggest that GIGA-2050 is safe and has a half-life similar to other recombinant human IgG1 antibodies. These results supported a successful investigational new drug application for GIGA-2050. This study demonstrates that a new class of drugs, recombinant hyperimmune globulins, can be manufactured consistently at the clinical scale and presents a new approach to treating infectious diseases that targets multiple epitopes of a virus.

    Abstract Mesenchymal stem cells (MSCs) have a large potential in cell therapy for treatment of inflammatory and autoimmune diseases, thanks to their immunomodulatory properties. The encouraging results in animal models have initiated the translation of MSC therapy to clinical trials. In cell therapy protocols with MSCs, administered intravenously, several studies have shown that a small proportion of infused MSCs can traffic to the draining lymph nodes (LNs). This is accompanied with an increase of different types of regulatory immune cells in the LNs, suggesting the importance of migration of MSCs to the LNs in order to contribute to immunomodulatory response. Intranodal (IN), also referred as intralymphatic, injection of cells, like dendritic cells, is being proposed in the clinic for the treatment of cancer and allergy, showing that this route of administration is clinically safe and efficient. In this study, we investigated, for the first time, the biodistribution and the efficacy of Luciferase

    Abstract Mesenchymal stem cells (MSCs) are multipotent stromal cells with immunomodulatory properties. They have emerged as a very promising treatment for autoimmunity and inflammatory diseases such as rheumatoid arthritis. Previous studies have demonstrated that MSCs, administered systemically, migrate to lymphoid tissues associated with the inflammatory site where functional MSC-induced immune cells with a regulatory phenotype were increased mediating the immunomodulatory effects of MSCs. These results suggest that homing of MSCs to the lymphatic system plays an important role in the mechanism of action of MSCs

    Abstract Background: Mesenchymal stem cells have potential applications in inflammatory bowel disease due to their immunomodulatory properties. Our aim was to evaluate the feasibility, safety and efficacy of endoscopic administration of adipose-derived mesenchymal stem cells (ASCs) in a colitis model in rats.
    Methods: Colitis was induced in rats by rectal trinitrobenzenesulfonic acid (TNBS). After 24 h ASCs (10
    Results: Endoscopic injection was successful in all the animals. No significant adverse events or mortality due to the procedure occurred. Weight evolution was significantly better in the ASC group, recovering initial weight by day 11 (- 0.8% ± 10.1%, mean ± SD), whereas the vehicle group remained in weight loss (- 6.7% ± 9.2%, p = 0.024). The endoscopic score improved in the ASC group by 47.1% ± 5.3% vs. 21.8% ± 6.6% in the vehicle group (p < 0.01). Stenosis was less frequent in the ASC group (4.8% vs. 41.2%, p < 0.01). Colon length significantly recovered in the ASC group versus the vehicle group (222.6 ± 17.3 mm vs. 193.6 ± 17.9 mm, p < 0.001). The endoscopic score significantly correlated with weight change, macroscopic necropsy score and colon length. Foxp3 and IL-10 mRNA levels in MLN recovered with ASC treatment.
    Conclusions: ASC submucosal endoscopic injection is feasible, safe and ameliorates TNBS-induced colitis in rats, especially stenosis.

    Abstract Background & aims: Crohn's disease is a chronic disease characterized by severe T-helper (Th)1 cell-driven inflammation of the colon partially caused by a loss of immune tolerance against mucosal antigens. Mesenchymal stem cells were recently described to suppress effector T-cell responses and have therapeutic effects in some immune disorders. Here, we investigated the potential therapeutic effects of human adipose-derived mesenchymal stem cells (hASCs) in a model of inflammatory bowel disease.
    Methods: Mice with trinitrobenzene sulfonic acid-induced colitis were treated with hASCs after onset of disease and clinical scores were evaluated. Inflammatory response was determined by measuring the levels of different inflammatory mediators in colon and serum. Th1-mediated effector responses were evaluated by determining the proliferation and cytokine profile of activated mesenteric lymph node cells. The number of regulatory T cells and the suppressive capacity on Th1 cell responses was determined.
    Results: Systemic infusion of hASCs or murine ASCs ameliorated the clinical and histopathologic severity of colitis, abrogating body weight loss, diarrhea, and inflammation and increasing survival (P < .001). This therapeutic effect was mediated by down-regulating both Th1-driven autoimmune and inflammatory responses. ASCs decreased a wide panel of inflammatory cytokines and chemokines and increased interleukin-10 levels (P < .001), directly acting on activated macrophages. hASCs also impaired Th1 cell expansion and induced/activated CD4(+)CD25(+)FoxP3(+) regulatory T cells with suppressive capacity on Th1 effector responses in vitro and in vivo (P < .001).
    Conclusions: hASCs emerge as key regulators of immune tolerance and as attractive candidates for a cell-based therapy for Crohn's disease.

    Abstract Objective: Rheumatoid arthritis (RA) is a chronic autoimmune disease caused by loss of immunologic self tolerance and characterized by chronic joint inflammation. Adult mesenchymal stem cells (MSCs) were recently found to suppress effector T cell responses and to have beneficial effects in various immune disorders. The purpose of this study was to examine a new therapeutic strategy for RA based on the administration of human adipose-derived MSCs (AD-MSCs).
    Methods: DBA/1 mice with collagen-induced arthritis were treated with human AD-MSCs after disease onset, and clinical scores were determined. Inflammatory response was determined by measuring the levels of different mediators of inflammation in the joints and serum. The Th1-mediated autoreactive response was evaluated by determining the proliferative response and cytokine profile of draining lymph node cells stimulated with the autoantigen. The number of Treg cells and the suppressive capacity on self-reactive Th1 cells were also determined.
    Results: Systemic infusion of human AD-MSCs significantly reduced the incidence and severity of experimental arthritis. This therapeutic effect was mediated by down-regulating the 2 deleterious disease components: the Th1-driven autoimmune and inflammatory responses. Human AD-MSCs decreased the production of various inflammatory cytokines and chemokines, decreased antigen-specific Th1/Th17 cell expansion, and induced the production of antiinflammatory interleukin-10 in lymph nodes and joints. Human AD-MSCs also induced de novo generation of antigen-specific CD4+CD25+FoxP3+ Treg cells with the capacity to suppress self-reactive T effector responses.
    Conclusion: Human AD-MSCs emerge as key regulators of immune tolerance by inducing the generation/activation of Treg cells and are thus attractive candidates for a cell-based therapy for RA.
