The switch/sucrose non-fermentable (SWI/SNF) chromatin remodeling complexes (also referred to as BAF complexes) are composed of multiple subunits, which regulate the nucleosome translocation and chromatin accessibility. In recent years, significant advancements have been made in understanding mutated genes encoding subunits of the SWI/SNF complexes in cancer biology. Nevertheless, the role of SWI/SNF complexes in immune response and inflammatory diseases continues to attract significant attention. This review presents a summary of the significant functions of SWI/SNF complexes during the overall process from the development to the activation of innate and adaptive immune cells. In addition, the correlation between various SWI/SNF subunits and diverse inflammatory diseases is explored. Further investigations are warranted in terms of the mechanism of SWI/SNF complexes' preference for binding sites and opposite pro-/anti-inflammatory effects. In conclusion, further efforts are needed to evaluate the druggability of targeting SWI/SNF complexes in inflammatory diseases, and we hope this review will inspire the development of novel immune modulators in clinical practice.

Introduction: Lorecivivint (LOR), a CDC-like kinase/dual-specificity tyrosine kinase (CLK/DYRK) inhibitor thought to modulate inflammatory and Wnt pathways, is being developed as a potential intra-articular knee osteoarthritis (OA) treatment. The objective of this trial was to evaluate long-term safety of LOR within an observational extension of two phase 2 trials.
Methods: This 60-month, observational extension study (NCT02951026) of a 12-month phase 2a trial (NCT02536833) and 6-month phase 2b trial (NCT03122860) was administratively closed after 36 months as data inferences became limited.
Background: The armamentarium of medical therapies to treat inflammatory bowel disease (IBD) continues to grow, which has expanded treatment options, particularly after first biologic failure. Currently, there are limited studies investigating the predictive value of first biologic primary non-response (PNR) on subsequent biologic success. Our objective was to determine if PNR to the first biologic for IBD is predictive of response to subsequent biologic therapy.

Chrysoeriol (CHE) is a naturally occurring compound with established anti-inflammatory and anti-tumor effects. This study examines its potential role in regulating osteoclast differentiation and activity, both of which are crucial for bone remodeling. Computational docking revealed high binding affinity between CHE and RANKL, specifically at the Lys-181 residue of RANKL, suggesting potential inhibitory interactions on osteoclastogenesis.

Cancer-associated fibroblasts (CAFs) significantly influence tumor progression and therapeutic resistance in colorectal cancer (CRC). However, the distributions and functions of CAF subpopulations vary across the four consensus molecular subtypes (CMSs) of CRC. This study performed single-cell RNA and bulk RNA sequencing and revealed that myofibroblast-like CAFs (myCAFs), tumor-like CAFs (tCAFs), inflammatory CAFs (iCAFs), CXCL14CAFs, and MTCAFs are notably enriched in CMS4 compared with other CMSs of CRC.
