Abstract
Costimulation blockade (CoB)-based immunotherapy is a promising alternative to immunosuppression for transplant recipients; however, the current limited understanding of the factors that impact its efficacy restrains its clinical applicability. In this context, pro- and anti-inflammatory cytokines are being recognized as having an impact on T cell activation beyond effector differentiation. This study aims at elucidating the impact of direct IL-10 signaling in T cells on CoB outcomes. We used a full-mismatch skin transplantation model where recipients had a T cell-restricted expression of a dominant negative IL-10 receptor (10R-DN), alongside anti-CD154 as CoB therapy. Unlike wild-type recipients, 10R-DN mice failed to benefit from CoB. This accelerated graft rejection correlated with increased accumulation of T cells producing TNF-α, IFN-γ, and IL-17. In vitro experiments indicated that while lack of IL-10 signaling did not change the ability of anti-CD154 to modulate alloreactive T cell proliferation, the absence of this pathway heightened TH1 effector cell differentiation. Furthermore, deficiency of IL-10 signaling in T cells impaired Treg induction, a hallmark of anti-CD154 therapy. Overall, these findings unveil an important and novel role of IL-10 signaling in T cells that defines the success of CoB therapies and identifies a target pathway for obtaining robust immunoregulation.

[PMID: 38366208 DOI: 10.1007/s11064-024-04121-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 01/18/2024] [Accepted: 02/04/2024] [Indexed: 02/18/2024]
Abstract
Spinal cord injury (SCI) encompasses various pathological processes, notably neuroinflammation and apoptosis, both of which play significant roles. CTLA-4, a well-known immune molecule that suppresses T cell-mediated immune responses, is a key area of research and a focal point for targeted therapy development in treating tumors and autoimmune disorders. Despite its prominence, the impact of CTLA-4 inhibition on inflammation and apoptosis subsequent to SCI remains unexplored. This study aimed to investigate the influence of CTLA-4 on SCI. A weight-drop technique was used to establish a rat model of SCI. To examine the safeguarding effect of CTLA-4 on the restoration of motor function in rats with SCI, the Basso-Beattie-Bresnahan (BBB) scale and inclined plane test were employed to assess locomotion. Neuronal degeneration and apoptosis were assessed using terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (TUNEL) and Fluoro-Jade B labeling, respectively, and the activity of microglial cells was examined by immunofluorescence. To evaluate the impact of CTLA4 on SCI, the levels of inflammatory markers were measured. After treatment with the CTLA-4 inhibitor ipilimumab, the rats showed worse neurological impairment and more severe neuroinflammation after SCI. Furthermore, the combination therapy with ipilimumab and durvalumab after SCI had more pronounced effects than treatment with either inhibitor alone. These findings indicate that CTLA-4 contributes to neuroinflammation and apoptosis after SCI, presenting a promising new therapeutic target for this traumatic condition.

Abstract
Solid organ transplant represents a potentially lifesaving procedure for patients suffering from end-stage heart, lung, liver, and kidney failure. However, rejection remains a significant source of morbidity and immunosuppressive medications have significant toxicities. Janus kinase (JAK) inhibitors are effective immunosuppressants in autoimmune diseases and graft versus host disease after allogeneic hematopoietic cell transplantation. Here we examine the role of JAK inhibition in preclinical fully major histocompatibility mismatched skin and heart allograft models. Baricitinib combined with cyclosporine A (CsA) preserved fully major histocompatibility mismatched skin grafts for the entirety of a 111-day experimental period. In baricitinib plus CsA treated mice, circulating CD4+T-bet+ T cells, CD8+T-bet+ T cells, and CD4+FOXP3+ regulatory T cells were reduced. Single cell RNA sequencing revealed a unique expression profile in immune cells in the skin of baricitinib plus CsA treated mice, including decreased inflammatory neutrophils and increased CCR2- macrophages. In a fully major histocompatibility mismatched mismatched heart allograft model, baricitinib plus CsA prevented graft rejection for the entire 28-day treatment period compared with 9 days in controls. Our findings establish that the combination of baricitinib and CsA prevents rejection in allogeneic skin and heart graft models and supports the study of JAK inhibitors in human solid organ transplantation.

Abstract
BACKGROUND Sporadic cases of rheumatoid arthritis (RA) due to unsatisfactory responses to Abatacept (ABT) have been reported; however, the rescue therapy has not been finalized. Here, we present a case with difficult-to-treat RA (D2T RA) that was resistant to either a single ABT or a Janus kinase (JAK) inhibitor (Tofacitinib), but improved with a combination of ABT and JAK inhibitor (Baricitinib, BAT).
CASE SUMMARY A 46-year-old Chinese woman who had RA for ten years that was resistant to Tocilizumab, Etanercept, Adalimumab, and ABT. According to the European League Against Rheumatism definition, the patient was diagnosed with D2T RA. It was then improved with a combination of ABT and a JAK inhibitor BAT.
CONCLUSION ABT combined with BAT may be an acceptable strategy for treating D2T RA.

Abstract
For the last few decades, Calcineurin inhibitors (CNI)-based therapy has been the pillar of immunosuppression for prevention of organ transplant rejection. However, despite exerting effective control of acute rejection in the first year post-transplant, prolonged CNI use is associated with significant side effects and is not well suited for long term allograft survival. The implementation of Costimulation Blockade (CoB) therapies, based on the interruption of T cell costimulatory signals as strategy to control allo-responses, has proven potential for better management of transplant recipients compared to CNI-based therapies. The use of the biologic cytotoxic T-lymphocyte associated protein 4 (CTLA4)-Ig is the most successful approach to date in this arena. Following evaluation of the BENEFIT trials, Belatacept, a high-affinity version of CTLA4-Ig, has been FDA approved for use in kidney transplant recipients. Despite its benefits, the use of CTLA4-Ig as a monotherapy has proved to be insufficient to induce long-term allograft acceptance in several settings. Multiple studies have demonstrated that events that induce an acute inflammatory response with the consequent release of proinflammatory cytokines, and an abundance of allograft-reactive memory cells in the recipient, can prevent the induction of or break established immunomodulation induced with CoB regimens. This review highlights advances in our understanding of the factors and mechanisms that limit CoB regimens efficacy. We also discuss recent successes in experimentally designing complementary therapies that favor CTLA4-Ig effect, affording a better control of transplant rejection and supporting their clinical applicability.

Abstract
Over the last 25 years, inhibition of Janus kinases (JAKs) has been pursued as a modality for treating various immune and inflammatory disorders. While the clinical development of JAK inhibitors (jakinibs) began with the investigation of their use in allogeneic transplantation, their widest successful application came in autoimmune and allergic diseases. Multiple molecules have now been approved for diseases ranging from rheumatoid and juvenile arthritis to ulcerative colitis, atopic dermatitis, graft-versus-host-disease (GVHD) and other inflammatory pathologies in 80 countries around the world. Moreover, two jakinibs have also shown surprising efficacy in the treatment of hospitalized coronavirus disease-19 (COVID-19) patients, indicating additional roles for jakinibs in infectious diseases, cytokine storms and other hyperinflammatory syndromes. Jakinibs, as a class of pharmaceutics, continue to expand in clinical applications and with the development of more selective JAK-targeting and organ-selective delivery. Importantly, jakinib safety and pharmacokinetics have been investigated alongside clinical development, further cementing the potential benefits and limits of jakinib use. This review covers jakinibs that are approved or are under late phase investigation, focusing on clinical applications, pharmacokinetic and safety profiles, and future opportunities and challenges.
