Understanding the pathogenesis of infectious diseases by single-cell RNA sequencing
August 4, 2021
This work highlights recent remarkable advances in single-cell RNA sequencing technologies and their applications in the investigation of host-pathogen interactions. Current challenges and potential prospects for disease treatment are discussed as well.
Regulation of anti-microbial autophagy by factors of the complement system
March 19, 2020
This review explores emerging evidence that components of the complement system, beyond their traditional immune roles, modulate autophagy - particularly xenophagy - thereby influencing cell-autonomous antimicrobial responses during host-pathogen interactions.
Protective roles of ginseng against bacterial infection
September 19, 2018
This review highlights the antibacterial effects of ginseng against pathogenic bacterial infections, discussing its regulation of pathogenic factors and proposing the therapeutic potential of ginseng as a natural antibacterial drug to address antibiotic resistance and toxicity in the context of global public health challenges.
Formyl-methionine as a degradation signal at the N-termini of bacterial proteins
September 6, 2015
Varshavsky and colleagues solve a long-standing mystery in proteolysis! In bacteria, all nascent proteins bear the pretranslationally formed N-terminal formyl-methionine (fMet) residue. The fMet residue is cotranslationally deformylated by a ribosome-associated deformylase. The formylation of N-terminal Met in bacterial proteins is not strictly essential for either translation or cell viability. Moreover, protein synthesis by the cytosolic ribosomes of eukaryotes does not involve the formylation of N-terminal Met. What, then, is the main biological function of this metabolically costly, transient, and not strictly essential modification of N‑terminal Met, and why has Met formylation not been eliminated during bacterial evolution? One possibility is that the similarity of the formyl and acetyl groups, their identical locations in...

Prokaryotic Argonautes – variations on the RNA interference theme
April 15, 2014
This article comments on work published by Swarts et al. (Nature, 2014), which demonstrates that Argonaute family protein of the bacterium Thermus thermophilus acts as a barrier for the uptake and propagation of foreign DNA.
Murals meet microbes: at the crossroads of microbiology and cultural heritage
December 6, 2021
This article comments on the duality of microorganisms in the conservation and restoration of cultural heritage, which encompasses the negative impact of damaging microorganisms and recent advances in using specific microorganisms and microbial-based technologies for cultural heritage preservation.
