Recent Advances in Biological Functions of Thick Pili in the Cyanobacterium Synechocystis sp. PCC 6803

Frontiers in Plant Science, 2020
Cyanobacteria have evolved various strategies to sense and adapt to biotic and abiotic stresses including active movement. Motility in cyanobacteria utilizing the type IV pili (TFP) is useful to cope with changing environmental conditions.

A Postbiotic‐Inducing Ganoderma applanatum Polysaccharide Repairs the Intestinal Barrier via a Phocaeicola vulgatus ‐ Tridecylic Acid Axis

Advanced Science, EarlyView.
This study identifies GAP2, a bioactive polysaccharide fraction derived from Ganoderma applanatum, as a postbiotic inducer that repairs intestinal barrier damage in a gut microbiota‐dependent manner. GAP2 enriches Phocaeicola vulgatus, which degrades GAP2 and promotes tridecylic acid production, triggering Rho/CDC42 signaling and tight‐junction ...

Evolution of a family of molecular Rube Goldberg contraptions.

PLoS Biology, 2019
Case studies of the evolution of molecular machines remain scarce. One of the most diverse and widespread homologous families of machines is the type IV filament (TFF) superfamily, comprised of type IV pili, type II secretion systems (T2SSs), archaella ...

Coordinated control of the type IV pili and c‐di‐GMP‐dependent antifungal antibiotic production in L ysobacter by the response regulator PilR

Molecular plant pathology, 2021
In the soil gammaproteobacterium Lysobacter enzymogenes, a natural fungal predator, the response regulator PilR controls type IV pili (T4P)‐mediated twitching motility as well as synthesis of the heat‐stable antifungal factor (HSAF).

Assessing the accuracy and stability of variable importance in species distribution modelling algorithms through sample perturbations

Ecography, EarlyView.
Variable importance derived from species distribution modelling (SDM) is widely used to identify key environmental drivers of species distributions. However, the reliability of these inferences has rarely been systematically evaluated, particularly with respect to their sensitivity to individual occurrences.

Microreview: type IV secretion systems: versatility and diversity in function [PDF]

, 2010
Type IV secretion systems (T4SSs) are large protein complexes which traverse the cell envelope of many bacteria. They contain a channel through which proteins or protein–DNA complexes can be translocated.

Cutaneous Leiomyosarcoma of the Head and Neck: Appreciation of a More Indolent Biological Behavior and Implications for Its Management

Head &Neck, EarlyView.
ABSTRACT Background Leiomysosarcoma (LMS) is generally associated with high metastatic potential and poor survival. Cutaneous LMS (cLMS) has been considered a different entity with more indolent biological behavior. Methods A narrative review was performed to assess the biological behavior of cLMS, with special attention for the head and neck location.
