TIM-3 on myeloid cells promotes pulmonary inflammation through increased production of galectin-3.

T cell immunoglobulin and mucin-containing molecule 3 (TIM-3) exhibits unique, cell type- and context-dependent characteristics and functions. Here, we report that TIM-3 on myeloid cells plays essential roles in modulating lung inflammation. We found that myeloid cell-specific TIM-3 knock-in (FSF-TIM3/LysM-Cre) mice have lower body weight and shorter lifespan than WT mice.

Galectin-9 Mediates the Functions of Microglia in the Hypoxic Brain Tumor Microenvironment.

Galectin-9 (Gal-9) is a multifaceted regulator of various pathophysiologic processes that exerts positive or negative effects in a context-dependent manner. In this study, we elucidated the distinctive functional properties of Gal-9 on myeloid cells within the brain tumor microenvironment (TME). Gal-9-expressing cells were abundant at the hypoxic tumor edge in the tumor-bearing ipsilateral hemisphere compared with the contralateral hemisphere in an intracranial mouse brain tumor model.

Factors Associated With Achieving Complete Skin Clearance Compared to Almost Complete Skin Clearance in Patients With Moderate to Severe Psoriasis Treated With Biologics: A Retrospective Chart Review.

Background: Biologics have demonstrated high efficacy in achieving 'almost complete' skin clearance in patients with moderate to severe psoriasis. Nonetheless, achieving 'complete' skin clearance remains a treatment goal for some highly biologics-resistant patients, as residual lesions impact their quality of life.

Objective: The risk factors for failure to achieve a Psoriasis Area and Severity Index (PASI) 100 response in patients with good response to biologics remain unknown.

Immune Checkpoint-Blocking Nanocages Cross the Blood-Brain Barrier and Impede Brain Tumor Growth.

Glioblastoma (GBM) is the deadliest tumor of the central nervous system, with a median survival of less than 15 months. Despite many trials, immune checkpoint-blocking (ICB) therapies using monoclonal antibodies against the PD-1/PD-L1 axis have demonstrated only limited benefits for GBM patients. Currently, the main hurdles in brain tumor therapy include limited drug delivery across the blood-brain barrier (BBB) and the profoundly immune-suppressive microenvironment of GBM.

A Case of Generalized Xerotic Eczema in a Patient with Congenital Insensitivity to Pain with Anhidrosis.

Congenital insensitivity to pain with anhidrosis (CIPA) is an extremely rare disease characterized by insensitivity to pain, anhidrosis, and intellectual disability. CIPA is caused by a genetic mutation in the neurotrophic tyrosine receptor kinase 1 () gene on chromosome 1. The anhidrosis leads to cutaneous changes such as skin dryness, lichenification, and impetiginization.

Characterization of a strain-specific CD-1 reference genome reveals potential inter- and intra-strain functional variability.

Background: CD-1 is an outbred mouse stock that is frequently used in toxicology, pharmacology, and fundamental biomedical research. Although inbred strains are typically better suited for such studies due to minimal genetic variability, outbred stocks confer practical advantages over inbred strains, such as improved breeding performance and low cost. Knowledge of the full genetic variability of CD-1 would make it more useful in toxicology, pharmacology, and fundamental biomedical research.

Recruitment of CTCF to an enhancer is responsible for transgenerational inheritance of BPA-induced obesity.

The mechanisms by which environmentally-induced epiphenotypes are transmitted transgenerationally in mammals are poorly understood. Here we show that exposure of pregnant mouse females to bisphenol A (BPA) results in obesity in the F2 progeny due to increased food intake. This epiphenotype can be transmitted up to the F6 generation.

Enhanced protein aggregation suppressor activity of N-acetyl-l-arginine for agitation-induced aggregation with silicone oil and its impact on innate immune responses.

Previously, N-acetyl-l-arginine (NALA) suppressed the aggregation of intravenous immunoglobulins (IVIG) more effectively and with a minimum decrease in transition temperature (T) than arginine monohydrochloride. In this study, we performed a comparative study with etanercept (commercial product: Enbrel®), where 25 mM arginine monohydrochloride (arginine) was added to the prefilled syringe. The biophysical properties were investigated using differential scanning calorimetry (DSC), dynamic light scattering (DLS), size-exclusion chromatography (SEC), and flow-imaging microscopy (FI).

Chromatin accessibility and transcription dynamics during in vitro astrocyte differentiation of Huntington's Disease Monkey pluripotent stem cells.

Background: Huntington's Disease (HD) is a fatal neurodegenerative disorder caused by a CAG repeat expansion, resulting in a mutant huntingtin protein. While it is now clear that astrocytes are affected by HD and significantly contribute to neuronal dysfunction and pathogenesis, the alterations in the transcriptional and epigenetic profiles in HD astrocytes have yet to be characterized. Here, we examine global transcription and chromatin accessibility dynamics during in vitro astrocyte differentiation in a transgenic non-human primate model of HD.

Maintenance of CTCF- and Transcription Factor-Mediated Interactions from the Gametes to the Early Mouse Embryo.

The epigenetic information present in mammalian gametes and whether it is transmitted to the progeny are relatively unknown. We find that many promoters in mouse sperm are occupied by RNA polymerase II (Pol II) and Mediator. The same promoters are accessible in GV and MII oocytes and preimplantation embryos.

Pach-ing It in: The Peculiar Organization of Mammalian Pachytene Chromosomes.

In this issue of Molecular Cell, Wang et al. (2019) use Hi-C to visualize at high resolution the complex reprogramming of chromatin architecture during spermatogenesis in rhesus monkeys and mice. They find that pachytene spermatocytes have a unique chromosome organization that may result from the presence of the synaptonemal complex and transcription-associated proteins.

Glial TLR2-driven innate immune responses and CD8 T cell activation against brain tumor.

Growing interest has been focused on the roles of microglia as sentinels and effector cells that guard diverse pathological milieu in the brain. Here, it has been reported that microglial TLR2 is a crucial molecule that confers innate and adaptive immunity against brain tumor. TLR2 is preferentially expressed on microglia, brain-resident immune cells, in the tumor-bearing cerebral hemisphere of mouse and rat intracranial tumor models.

JIB-04, A Small Molecule Histone Demethylase Inhibitor, Selectively Targets Colorectal Cancer Stem Cells by Inhibiting the Wnt/β-Catenin Signaling Pathway.

Although several epigenetic modulating drugs are suggested to target cancer stem cells (CSCs), additional identification of anti-CSC drugs is still necessary. Here we showed that JIB-04, a pan-selective inhibitor of histone demethylase(s), was identified as a small molecule that selectively target colorectal CSCs. Our data showed that JIB-04 is capable of reducing self-renewal and stemness of colorectal CSCs in three different colorectal cancer cell lines.
