A Zebrafish Model of Mycobacterium leprae Granulomatous Infection. [PDF]

, 2017
Understanding the pathogenesis of leprosy granulomas has been hindered by a paucity of tractable experimental animal models. Mycobacterium leprae, which causes leprosy, grows optimally at approximately 30°C, so we sought to model granulomatous disease in

Tissue‐Resident Macrophage‐Derived E3 Ligase SMURF2 Restricts Autoimmune Inflammation by Mediating the Degradation of p‐TBK1

Advanced Science, EarlyView.
Dysregulated Tissue resident macrophage (TRMs) link to autoimmune inflammation. SMURF2 mediates Lys‐27 (K27)‐linked ubiquitination of p‐TBK1 and its degradation, which inhibits CSF1R signaling‐triggered TRM proliferation, thereby restraining the autoimmune inflammation.

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

Advanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.

A truncated lipoglycan from mycobacteria with altered immunological properties [PDF]

, 2010
Maintenance of cell-wall integrity in Mycobacterium tuberculosis is essential and is the target of several antitubercular drugs. For example, ethambutol targets arabinogalactan and lipoarabinomannan (LAM) biosynthesis through the inhibition of several ...

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

Advanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

Advanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.
