However, its relationship with maternal age-associated decline in oocyte quality remains elusive. Here, we report that establishment of gut microbiota from young donors in aged mice by fecal microbiota transplantation (FMT) is an effective method to rejuvenate the quality of maternally aged oocytes. Specifically, young gut microbiota promoted the ovulation and maturation of aged oocytes, and inhibited occurrence of cytoplasm fragmentation and spindle/chromosome abnormalities, hence enhancing the oocyte quality and female fertility. By integrating metagenome and untargeted metabolome of intestinal digesta, as well as targeted metabolome of ovaries and micro-transcriptome of oocytes, we identified that Bacteroides_caecimuris-modulated glutamic acid levels mediated the restorative effects of young gut microbiota on the aged oocytes through strengthening the mitochondria function. In addition, we demonstrated that in vivo supplementation of glutamic acid also enhanced the quality of aged oocytes, and the improvement of oocyte quality by glutamic acid was conserved across species.

Here, we demonstrate that costimulation blockade paradoxically potentiates IL-2-driven Treg generation by selectively reprogramming intracellular cytokine signaling. We identified that IL-2 activates STAT3 only in the presence of TCR stimulation, as this pathway requires CD28-mediated PI3K-AKT signaling, which is abrogated by costimulation blockade. Consequently, CTLA-4 Ig uncouples STAT3 activation from IL-2 signaling while sparing STAT5, thereby enhancing TGF-β/Smad2/3 signaling to induce Foxp3 expression. This dual action-sustained STAT5 activation and increased Smad2/3 signaling-promoted robust Treg generation that ameliorated experimental autoimmune encephalomyelitis (EAE). Furthermore, we confirmed that this synergistic effect is conserved in human T cells from patients with multiple sclerosis (MS) upon CTLA-4 Ig and IL-2 cotreatment.

Here, a complementary perspective is proposed: epidermal homeostasis and disease recurrence may also depend on the physical organization of the genome within the nucleus. HNRNPU/SAF-A has emerged as an RNA-dependent architectural factor that links RNA binding to chromatin topology, while architectural long non-coding RNAs provide precedents for how RNA can scaffold nuclear compartments and influence higher-order genome organization. Building on these concepts, the Epidermal Differentiation Complex is considered as a tractable epidermal locus in which RNA-dependent nuclear tethering may help stabilize barrier gene programs. This framework further suggests that chronic inflammation could remodel chromatin architecture in ways that persist after apparent resolution, generating a \"structural scar\" that biases future responses. Although this model remains hypothetical, it is now experimentally testable.

Emerging evidence indicates that loss or reduced expression of CD19-due to mutations, deletions, alternative splicing-is a significant, underrecognized mechanism of treatment failure. Notably, CD19-negative subpopulations can be detected even prior to therapy, and patients with low CD19 expression consistently show poorer outcomes. Although current clinical guidelines do not mandate routine CD19 testing before treatment, this situation reflects both scientific and technical challenges. Importantly, patients with partial/ low CD19 expression may still benefit from therapy, complicating the definition of \"target positivity.\" From a regulatory perspective, targeted therapies should ideally be used only when target expression is confirmed. This principle is difficult to implement, considering the scarcity of data and the difficulties of current diagnostic tools, risking both undertreatment and overtreatment.
