Human Colitis‐on‐Chip Model Reveals Dual Roles of Butyrate in Epithelial and Macrophage Defense Against Candida albicans Tissue Invasion

Small, EarlyView.
This study establishes a human immunocompetent colitis‐on‐chip model that mimics inflamed gut mucosa and enables quantitative analysis of Candida albicans tissue invasion under DSS‐induced injury. It reveals that microbiota‐derived butyrate simultaneously stabilizes epithelial junctions and reprograms macrophages via HDAC/NLRP3‐dependent mechanisms ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

PLGA‐particle‐based vaccine induces SARS‐CoV‐2‐specific antibody and T‐cell responses

British Journal of Pharmacology, EarlyView.
A novel coronavirus disease 2019 (COVID‐19) vaccine encapsulating recombinant severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) spike receptor binding domain (RBD) with the double stranded RNA (dsRNA) analogue Riboxxim induces robust systemic and respiratory T‐ and B‐cell responses in mice.

Gasdermin‐Mediated Pyroptosis: Novel Strategies Against Colorectal Cancer

Cancer Science, EarlyView.
Pyroptosis is a double‐edged sword in colorectal cancer (CRC): chronic low‐grade pyroptosis promotes tumor progression, whereas acute induction of pyroptosis in cancer cells triggers antitumor immunity and enhances therapeutic response. Targeting gasdermin‐mediated pyroptosis represents a promising strategy for CRC treatment.

Irradiated Liver Cancer Cell Vaccine Transfected With GM‐CSF Induces Specific and Long‐Lasting Anti‐tumour Immunity Through the Synergistic Effect of Oxidised mtDNA and GM‐CSF

Cell Proliferation, EarlyView.
Song et al. developed an mGM‐CSF‐loaded, liver cancer cell‐based vaccine that potently activated dendritic cells and elicited tumour‐specific T cell responses. Mechanistically, radiation‐induced oxidative damage to mitochondrial DNA in cancer cells triggers the cGAS‐STING pathway in DCs, which synergizes with mGM‐CSF‐driven JAK2‐STAT3 signalling to ...

Dual-RNA-sequencing to elucidate the interactions between sorghum and Colletotrichum sublineola

Frontiers in Fungal Biology
In warm and humid regions, the productivity of sorghum is significantly limited by the fungal hemibiotrophic pathogen Colletotrichum sublineola, the causal agent of anthracnose, a problematic disease of sorghum (Sorghum bicolor (L.) Moench) that can ...

Monocytes Derived From Human Pluripotent Stem Cells Engineered for Detection of Pyrogens

Cell Proliferation, EarlyView.
In summary, we have developed a monocyte‐based reporter system using hESC‐Mono for interrogating the NF‐κB signalling axis, a central pathway governing pyrogenic responses. Our platform enables rapid and dose‐dependent detection of both endotoxins (LPS) and non‐endotoxins (LTA and Zymosan).

Molecular characterisation of the underlying mechanisms of pathogen-associated molecular pattern (PAMP) recognition in fish

, 2011
The innate immune response is based upon the activation of a restricted number of genotypic encoded receptors, the pathogen recognition receptors (PRRs). PRRs can be soluble proteins such as plasmatic PGRPs or cell membraneanchored TLRs able to recognize pathogens or their pathogen-associated molecular patterns (PAMPs).

Pathogen-associated molecular patterns (PAMPs) derived from Leishmania and bacteria increase gene expression of antimicrobial peptides and gut surface proteins in sand flies

International Journal for Parasitology
The interaction between pathogens and vectors' physiology can impact parasite transmission. Studying this interaction at the molecular level can help in developing control strategies. We study leishmaniases, diseases caused by Leishmania parasites transmitted by sand fly vectors, posing a significant global public health concern. Lipophosphoglycan (LPG)

Erosive pustular dermatosis of the lower legs (EPDL): A rarely diagnosed neutrophilic dermatosis of the elderly

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Erosive pustular dermatosis of the lower legs (EPDL) is a rarely diagnosed, chronic inflammatory skin disease that occurs predominantly in elderly people. Predisposing factors include skin atrophy, chronic venous insufficiency, and trauma. Although the pathogenesis of EPDL has not yet been conclusively clarified, there are ongoing discussions ...
