Chemotherapy‐Mediated Induction of PD‐L1 via SEI1 Facilitates Myeloma Immune Evasion

Advanced Science, EarlyView.
Chemotherapy induces DNA damage, activating cyclic guanosine monophosphate (GMP)‐adenosine monophosphate (AMP) synthase (cGAS)/stimulator of interferon genes (STING), which phosphorylates interferon regulatory factor 7 (IRF7) to drive SERTA‐containing domain 1 (SEI1) transcription.

Barrier-Free Microhabitats: Self-Organized Seclusion in Microbial Communities [PDF]

arXiv
Bacteria frequently colonize natural microcavities such as gut crypts, plant apoplasts, and soil pores. Recent studies have shown that the physical structure of these spaces plays a crucial role in shaping the stability and resilience of microbial populations (Karita et al., PNAS 2022, Postek et al. PNAS 2024).

Gut Microbiota‐Butyrate‐PPARγ Axis Modulates Adipose Regulatory T Cell Population

Advanced Science, EarlyView.
This study identifies the indispensable role of gut microbiota in the maintenance of ST2+ adipose Treg cell population, and defines gut microbiota‐derived butyrate as an endogenous PPARγ agonist, modulating adipose Treg cell populations via promoting PPARγ activation. Butyrate or fiber supplementation restores the VAT ST2+ Treg population in obese mice

Structure, function and diversity of the healthy human microbiome [PDF]

, 2012
Studies of the human microbiome have revealed that even healthy individuals differ remarkably in the microbes that occupy habitats such as the gut, skin and vagina. Much of this diversity remains unexplained, although diet, environment, host genetics and

Targeting the Adenosine‐Mediated Metabolic Immune Checkpoint with Engineered Probiotic for Enhanced Chemo‐Immunotherapy

Advanced Science, EarlyView.
This study presents engineered probiotics that convert immunosuppressive adenosine into inosine in tumors, alleviating immunosuppression and enhancing antitumor immunity. Demonstrating efficacy in murine ectopic and orthotopic tumor models, this approach offers a promising probiotic‐based cancer immunotherapy strategy, highlighting the potential of ...

Foundations for reconstructing early microbial life [PDF]

arXiv
For more than 3.5 billion years, life experienced dramatic environmental extremes on Earth. These include shifts from oxygen-less to over-oxygenated atmospheres and cycling between hothouse conditions and global glaciations. Meanwhile, an ecological revolution took place.

Orally Administered Functional Polyphenol‐Nanozyme‐Armored Probiotics for Enhanced Amelioration of Intestinal Inflammation and Microbiota Dysbiosis

Advanced Science, EarlyView.
This study presents a novel polyphenol‐nanozyme‐armored probiotic system (ECA@EcN) for enhanced treatment of inflammatory bowel disease (IBD). By integrating chitosan‐modified epigallocatechin gallate (EGCG‐CS) with gold nanozymes, the system effectively scavenges ROS, improves probiotic viability, and restores gut microbiota balance.

Low‐Irradiance Antimicrobial Blue Light‐Bathing Therapy for Wound Infection Control

Advanced Science, EarlyView.
Antimicrobial blue light has been shown as an appealing non‐pharmacological antimicrobial alternative. However, its clinical applications have been hindered by high irradiance‐associated photothermal risks. In this work, a low‐irradiance blue light‐bathing concept and a wearable photonic wound patch are established to address this challenge in terms of

Structure Elucidation, Total Synthesis, Antibacterial In Vivo Efficacy and Biosynthesis Proposal of Myxobacterial Corramycin**

Angewandte Chemie International Edition, Volume 61, Issue 51, December 19, 2022., 2022
Corramycin is a novel natural product produced by the myxobacterium Corallococcus coralloides. The structure, extraordinary total synthesis and biosynthesis of the antibiotic is described for the first time. Its promise as an in vivo septicemia model, the absence of cross‐resistance with commonly used antibiotic classes, and the lack of cytotoxicity ...
