Peripheral nerve-derived CSF1 induces BMP2 expression in macrophages to promote nerve regeneration and wound healing.

The precise mechanisms regulating inflammatory and prorepair macrophages have not been fully elucidated, despite the pivotal role played by innate immunity in wound healing. We first employed a denervation wound model to validate the crosstalk between neurons and macrophages. Compared to normal wound healing, the denervation wound healing process involved fewer macrophages, decreased angiogenesis, and delayed wound healing.

Recombinant humanized type III collagen inhibits ovarian cancer and induces protective anti-tumor immunity by regulating autophagy through GSTP1.

Ovarian cancer (OC) is one of the leading causes of death from malignancy in women and lacks safe and efficient treatment. The novel biomaterial, recombinant humanized collagen type III (rhCOLIII), has been reported to have various biological functions, but its role in OC is unclear. This study aimed to reveal the function and mechanism of action of rhCOLIII in OC.

Recombinant humanized type I collagen remodels decidual immune microenvironment at maternal-fetal interface by modulating Th17/Treg imbalance.

Disruption of the extracellular matrix and dysregulation of the balance between Th17 and regulatory T cells are recognized as risk factors for recurrent spontaneous abortion (RSA). However, the interaction between matrix components and the Th17/Treg axis remains poorly elucidated. The result of this study revealed that the absence of type I collagen in the decidua is linked to Th17/Treg imbalance in RSA.

Construction of a novel "self-regenerative" electrochemical biosensor based on metal-organic frameworks and its application to the detection of Mycoplasma ovine pneumonia.

This study aimed to prepare a novel "self-regenerative" electrochemical biosensor by successively modifying gold nanoparticles, four-arm polyethylene glycol-NH, and NH-MIL-53 (Al) (MOF) on the glassy carbon electrode interface. A hairpin G-triplex-mediated DNA (G3 probe) as a part of the mycoplasma ovine pneumonia (MO) gene was loosely adsorbed to MOF. Based on the mechanism of hybridization induction, the G3 probe could effectively detach from the MOF only after introducing the target DNA.

Hybridization-driven fluorometric platform based on metal-organic frameworks for the identification of the highly homologous viruses.

A novel fluorometric strategy for the simultaneous identification of SARS-CoV-2 and SARS-CoV was successfully established based on a hybridization-induced signal on-off-on mechanism. Here, one part of the probe (P1) of SARS-CoV-2 (P = P1/P2) is partially related to SARS-CoV, while the other part (P2) is completely irrelevant to SARS-CoV. They as smart gatekeepers were anchored on NH-MIL-88(Fe) (MOF@P1/P2) to turn off its catalytic performance.

Poly cytosine (C)/poly adenine (A) modified probe for signal "on-off-on" assay of single-base mismatched dsDNA by a competitive mechanism.

Direct discrimination of single-base mismatched dsDNA by a simple method or strategy would provide enormous opportunities for applications in the fields of life sciences and disease diagnosis. Herein, the peroxidase-mimicking activity of a metal-organic framework nanoprobe (MOF) was well exploited for the direct discrimination of single-base mismatched dsDNA based on a competition-induced signal on-off-on mechanism. The single-base mismatched dsDNA related with FecB gene (usually guanine (G)/thymine (T) mismatch) and MIL-88B-NH were used as target and MOF model, respectively.

GAS6-mediated dialogue between decidual stromal cells and macrophages is essential for early pregnancy maintenance by inducing M2-like polarization and cell proliferation of decidual macrophages.

Maternal immunotolerance towards the semi-allogeneic foetus is critical for normal pregnancy (NP). As a secretory protein, growth arrest-specific factor 6 (GAS6) promotes cancer progression by inducing the conversion of tumour-associated macrophages to an immunosuppressive M2-like phenotype. However, little is known about whether GAS6 regulates decidual macrophages (dMφs) in the early maternal-foetal interface.

Intravaginal Administration of Human Type III Collagen-Derived Biomaterial with High Cell-Adhesion Activity to Treat Vaginal Atrophy in Rats.

Vaginal atrophy (VA) is the thinning and drying of the vaginal walls, which can lead to a variety of symptoms. VA is usually initiated by decreasing estrogen levels in post-menopausal women; so, the traditional treatment of VA is hormone therapy (HT). Here, we sought nonhormonal therapies aimed at treating this condition safely and effectively.
