BolA Is Required for the Accurate Regulation of c-di-GMP, a Central Player in Biofilm Formation [PDF]

, 2017
The bacterial second messenger cyclic dimeric GMP (c-di-GMP) is a nearly ubiquitous intracellular signaling molecule involved in the transition from the motile to the sessile/biofilm state in bacteria.

Laparoscopic Delivery of a MnO2‐P‐ICG Patch for Photodynamic Therapy and NK Cell‐Driven Immunotherapy in Hepatocellular Carcinoma

Advanced Science, EarlyView.
This study proposes a flexible MnO2‐P‐ICG nanofiber patch for laparoscopic treatment of liver tumors. The patch alleviates tumor hypoxia and induces photodynamic therapy (PDT) triggered immunogenic cell death, thereby activating the cGAS‐STING pathway and, in synergy with pachymaran, promoting NK cell–mediated innate immunity. This synergistic strategy

The Diguanylate Cyclase SadC Is a Central Player in Gac/Rsm-Mediated Biofilm Formation in Pseudomonas aeruginosa

, 2014
Pseudomonas aeruginosa is a Gram-negative opportunistic human pathogen and a threat for immune-compromised and Cystic Fibrosis patients. It is responsible for acute and chronic infections and can switch between these lifestyles upon taking an informed ...

Senomorphic Small Extracellular Vesicles Delivered by a Tissue‐Adhesive α‐Lipoic‐Acid Hydrogel Enable Immuno‐Rejuvenation for Bone‐Tendon Interface Regeneration

Advanced Science, EarlyView.
This work identifies M1 macrophage‐mediated inflammation as a key driver of BMSC senescence and bone microstructural deterioration at the enthesis. A tissue‐adhesive hydrogel delivering senomorphic small extracellular vesicles suppresses this inflammatory‐senescent cascade and enhances BMSC resilience by inhibiting the cGAS‐STING‐NF‐κB pathway.

Efficient Enzymatic Production of the Bacterial Second Messenger c-di-GMP by the Diguanylate Cyclase YdeH from E. coli [PDF]

, 2018
Cyclic di-GMP (c-di-GMP) is an almost universal bacterial second messenger involved in the regulation of cell surface-associated traits and the persistence of infections.

PAIR: Reconstructing Single‐Cell Open‐Chromatin Landscapes for Transcription Factor Regulome Mapping

Advanced Science, EarlyView.
scATAC‐seq analysis is often constrained by limited sequencing depth, extreme sparsity, and pervasive technical missingness. PAIR is a probabilistic framework that restores scATAC‐seq accessibility profiles by directly modeling the native cell–peak bipartite structure of chromatin accessibility.

Coincidence detection and bi-directional transmembrane signaling control a bacterial second messenger receptor

eLife, 2016
The second messenger c-di-GMP (or cyclic diguanylate) regulates biofilm formation, a physiological adaptation process in bacteria, via a widely conserved signaling node comprising a prototypical transmembrane receptor for c-di-GMP, LapD, and a cognate ...

Inflammation-induced DNA damage and damage-induced inflammation: a vicious cycle [PDF]

, 2014
Inflammation is the ultimate response to the constant challenges of the immune system by microbes, irritants or injury. The inflammatory cascade initiates with the recognition of microorganism-derived pathogen associated molecular patterns (PAMPs) and ...

Lyophilized Synthetic Platelets: In Vitro Characterization and in Vivo Evaluation in Mouse Thrombocytopenia Model

Advanced Science, EarlyView.
ABSTRACT Platelet transfusions to treat bleeding complications use donor‐derived platelets stored at room‐temperature, that have a shelf‐life of only 5–7 days due to bacterial contamination risks. Cold‐stored and freeze‐dried platelets are being investigated for extending shelf‐life, but these still have the inherent challenge of donor‐dependency.

Tumor‐Induced Splenic Remodeling: Mechanisms of Systemic Immunosuppression and Emerging Therapeutic Opportunities

Advanced Science, EarlyView.
ABSTRACT Despite the transformative impact of cancer immunotherapies such as immune checkpoint blockade, durable clinical responses remain limited. Increasing evidence indicates that antitumor immunity is governed not only by the tumor microenvironment, but also by systemic immune regulation mediated by peripheral immune organs. Among these, the spleen
