Lipoic acid improves wound healing through its immunomodulatory and anti-inflammatory effects in a diabetic mouse model.

Objectives: Diabetes mellitus is a chronic disease that has become more prevalent worldwide because of lifestyle changes. It leads to serious complications, including increased atherosclerosis, protein glycosylation, endothelial dysfunction, and vascular denervation. These complications impair neovascularization and wound healing, resulting in delayed recovery from injuries and an elevated risk of infections.

Langerhans Cells Drive Tfh and B Cell Responses Independent of Canonical Cytokine Signals.

Unlabelled: Dendritic cells (DCs) are key regulators of adaptive immunity, guiding T helper (Th) cell differentiation through antigen presentation, co-stimulation, and cytokine production. However, in steady-state conditions, certain DC subsets, such as Langerhans cells (LCs), induce T follicular helper (Tfh) cells and B cell responses without inflammatory stimuli. Using multiple mouse models and systems, we investigated the mechanisms underlying steady-state LC-induced adaptive immune responses.

IL-9 as a naturally orthogonal cytokine with optimal JAK/STAT signaling for engineered T cell therapy.

Arming T cells with a synthetically orthogonal IL-9 receptor (o9R) permits facile engraftment and potent anti-tumor functions. We considered whether the paucity of natural IL-9R expression could be exploited for T cell immunotherapy given that, in mice, high doses of IL-9 were well-tolerated without discernible immune modulation. Compared to o9R, T cells engineered with IL-9R exhibit superior tissue infiltration, stemness, and anti-tumor activity.

Insights into the Absence of Lymphoma Despite Fulminant Epstein-Barr Virus Infection in Patients with XIAP Deficiency.

Unlabelled: X-linked Lymphoproliferative Syndromes (XLP), which arise from mutations in the or genes, are characterized by the inability to control Epstein-Barr Virus (EBV) infection. While primary EBV infection triggers severe diseases in each, lymphomas occur at high rates with XLP-1 but not with XLP-2. Why XLP-2 patients are apparently protected from EBV-driven lymphomagenesis, in contrast to all other described congenital conditions that result in heightened susceptibility to EBV, remains a key open question.

The emerging fungal pathogen induces IFNγ to colonize mammalian hair follicles.

Public health alarm concerning the emerging fungus is fueled by its antifungal drug resistance and propensity to cause deadly outbreaks.

We compared the skin colonization dynamics of with its relative , quantifying skin fungal persistence and distribution and immune composition and positioning.

Physiologically Relevant Coculture Model for Oral Microbial-Host Interactions.

Understanding microbial-host interactions in the oral cavity is essential for elucidating oral disease pathogenesis and its systemic implications. bacteria-host cell coculture models have enabled fundamental studies to characterize bacterial infection and host responses in a reductionist yet reproducible manner. However, existing coculture models fail to replicate the physiological oxygen gradients critical for studying these interactions.

IL-27 limits HSPC differentiation during infection and protects from stem cell exhaustion.

Many inflammatory stimuli can induce progenitor cells in the bone marrow to produce increased numbers of myeloid cells as part of the process of emergency myelopoiesis. These events are associated with innate training and can have long-term impacts on hematopoietic stem and progenitor cell (HSPC) development but can also compromise their function. While many cytokines support emergency myelopoiesis, less is known about the mechanisms that temper these events.

IL-21-STAT3 axis negatively regulates LAIR1 expression in B cells.

LAIR1 is an inhibitory receptor broadly expressed on human immune cells, including B cells. LAIR1 has been shown to modulate BCR signaling, however, it is still unclear whether its suppressive activity can be a negative regulator for autoreactivity. In this study, we demonstrate the LAIR1 expression profile on human B cells and prove its regulatory function and relationships to B cell autoreactivity.

Harnessing Extracellular Vesicles for Stabilized and Functional IL-10 Delivery in Macrophage Immunomodulation.

Extracellular vesicles (EVs) are gaining recognition as promising therapeutic carriers for immune modulation. We investigated the potential of EVs derived from HEK293FT cells to stabilize and deliver interleukin-10 (IL-10), a key anti-inflammatory cytokine. Using minicircle (MC) DNA vectors, we achieved IL-10 overexpression and efficient incorporation into EVs, yielding superior stability compared to free, recombinant IL-10 protein.

Inflammation and Immune Escape in Ovarian Cancer: Pathways and Therapeutic Opportunities.

Ovarian cancer (OC) remains one of the most lethal gynecological malignancies, largely due to its late-stage diagnosis and high recurrence rates. Chronic inflammation is a critical driver of OC progression, contributing to immune evasion, tumor growth, and metastasis. Inflammatory cytokines, including IL-6, TNF-α, and IL-8, as well as key signaling pathways such as nuclear factor kappa B (NF-kB) and signal transducer and activator of transcription 3 (STAT3), are upregulated in OC, promoting a tumor-promoting environment.

Infiltrating lipid-rich macrophage subpopulations identified as a regulator of increasing prostate size in human benign prostatic hyperplasia.

Introduction: Macrophages exhibit marked phenotypic heterogeneity within and across disease states, with lipid metabolic reprogramming contributing to macrophage activation and heterogeneity. Chronic inflammation has been observed in human benign prostatic hyperplasia (BPH) tissues, however macrophage activation states and their contributions to this hyperplastic disease have not been defined. We postulated that a shift in macrophage phenotypes with increasing prostate size could involve metabolic alterations resulting in prostatic epithelial or stromal hyperplasia.

Inhibition of hippocampal interleukin-6 receptor-evoked signalling normalises long-term potentiation in dystrophin-deficient mice.

Duchenne muscular dystrophy (DMD), an X-linked neuromuscular disorder, characterised by progressive immobility, chronic inflammation and premature death, is caused by the loss of the mechano-transducing signalling molecule, dystrophin. In non-contracting cells, such as neurons, dystrophin is likely to have a functional role in synaptic plasticity, anchoring post-synaptic receptors. Dystrophin-expressing hippocampal neurons are key to cognitive functions such as emotions, learning and the consolidation of memories.
