Abstract
Psoriatic arthritis (PsA) is a chronic inflammatory arthropathy affecting the skin, entheses, and joints. Over the past decade, experimental evidence has revealed the activation of several immune cells and signaling cascades in modulating the pathophysiology of PsA. Recently, targeted therapies have been developed to combat the severity of disease. However, with diverse etiologies, flareups, and relapses, there has been an increased prevalence and mortality associated with PsA in recent years. Therefore, it is imperative to investigate new potential mediators and combination therapies to manage PsA pathogenesis. IL-21, an immunomodulatory cytokine, has pleiotropic effects on immune cells and the protein cascades involved in PsA pathogenesis. Recently, emerging evidence of increased IL-21 levels in patients with PsA has engendered much enthusiasm for its potential as a therapeutic target. Here, we unmasked IL-21 as a significant modulator of PsA pathogenesis and reviewed the comorbidities associated with the disease, further cataloging future therapeutic modalities to ameliorate PsA progression.

Abstract
Chimeric antigen receptor T (CAR-T) cell therapy, as an adoptive immunotherapy, is playing an increasingly important role in the treatment of malignant tumors. CAR-T cells are referred to as "living drugs" as they not only target tumor cells directly, but also induce long-term immune memory that has the potential to provide long-lasting protection. CD19.CAR-T cells have achieved complete response rates of over 90 % for acute lymphoblastic leukemia and over 60 % for non-Hodgkin's lymphoma. However, the response rate of CAR-T cells in the treatment of solid tumors remains extremely low and the side effects potentially severe. In this review, we discuss the limitations that the solid tumor microenvironment poses for CAR-T application and the solutions that are being developed to address these limitations, in the hope that in the near future, CAR-T cell therapy for solid tumors can attain the same success rates as are now being seen clinically for hematological malignancies.

Int J Mol Sci 2023; 24:12557. [PMID: 37628738 PMCID: PMC10454239 DOI: 10.3390/ijms241612557] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 08/03/2023] [Accepted: 08/04/2023] [Indexed: 08/27/2023] Open
Abstract
Interleukin-21 and its receptors (IL-21/IL-21R) aggravate chlamydial lung infection, while macrophages (Mφ) are one of the main cells infected by chlamydia and the main source of inflammatory cytokines. Therefore, it is particularly important to study whether IL-21/IL-21R aggravates chlamydia respiratory infection by regulating Mφ. Combined with bioinformatics analysis, we established an IL-21R-deficient (IL-21R-/-) mouse model of Chlamydia muridarum (C. muridarum) respiratory tract infection in vivo, studied C. muridarum-stimulated RAW264.7 by the addition of rmIL-21 in vitro, and conducted adoptive transfer experiments to clarify the association between IL-21/IL-21R and Mφ. IL-21R-/- mice showed lower infiltration of pulmonary total Mφ, alveolar macrophages, and interstitial macrophages compared with WT mice following infection. Transcriptomic analysis suggested that M1-related genes are downregulated in IL-21R-/- mice and that IL-21R deficiency affects the Mφ-mediated inflammatory response during C. muridarum infection. In vivo experiments verified that in IL-21R-/- mice, pulmonary M1-type CD80+, CD86+, MHC II+, TNFα+, and iNOS+ Mφ decreased, while there were no differences in M2-type CD206+, TGF-β+, IL-10+ and ARG1+ Mφ. In vitro, administration of rmIL-21 to C. muridarum-stimulated RAW264.7 cells promoted the levels of iNOS-NO and the expression of IL-12p40 and TNFα, but had no effect on TGFβ or IL-10. Further, adoptive transfer of M1-like bone marrow-derived macrophages derived from IL-21R-/- mice, unlike those from WT mice, effectively protected the recipients against C. muridarum infection and induced relieved pulmonary pathology. These findings help in understanding the mechanism by which IL-21/IL-21R exacerbates chlamydia respiratory infection by promoting the proinflammatory effect of Mφ.

Abstract
FcγRI is an important cell surface receptor reported to be involved in multiple immune responses, although it has not yet been extensively studied in intracellular bacterial infections. Here, using a mouse model of C. muridarum respiratory infection, we were able to determine how FcγRI regulates the host resistance against chlamydial invasion. According to our findings, the chlamydial loads and pulmonary pathology were both reduced in FcγRI deficient (Fcgr1-/-) animals. Being infected, monocytes, macrophages, neutrophils, DCs, CD4+/CD8+ T cells, and effector Th1 subsets displayed increased FcγRI expression patterns. Altered infiltration of these cells in the lungs of Fcgr1-/- mice further demonstrated the regulation of FcγRI in the immune system and identified Th1 cells and macrophages as its target cell populations. As expected, we observed that the Th1 response was augmented in Fcgr1-/- mice, while the pro-inflammatory M1 macrophage polarization was constrained. These findings might indicate FcγRI as a potential regulator for host immunity and inflammatory response during chlamydial infection.
