Background: , which are filamentous cyanobacteria, have gained significant popularity in the food industry, medicine, and aquaculture.
Methods: In this study, our objective was to explore the influence of on the gut microbiota and exercise capacity of mice undergoing high-intensity exercise. Twenty-four male BALB/c mice were divided into four groups, with six mice in each group.

Nucleoside triphosphate (NTP)-dependent protein assemblies such as microtubules and actin filaments have inspired the development of diverse chemically fueled molecular machines and active materials but their functional sophistication has yet to be matched by design. Given this challenge, we asked whether it is possible to transform a natural adenosine 5'-triphosphate (ATP)-dependent enzyme into a dissipative self-assembling system, thereby altering the structural and functional mode in which chemical energy is used. Here we report that FtsH (filamentous temperature-sensitive protease H), a hexameric ATPase involved in membrane protein degradation, can be readily engineered to form one-dimensional helical nanotubes.

Background: Scedosporium apiospermum is a multidrug-resistant filamentous fungus that causes localized and disseminated diseases. Our group has previously described that metalbased complexes containing copper(II) or silver(I) ions complexed with 1,10-phenanthroline-5,6- dione (phendione) inhibited the viability of S. apiospermum conidial cells.

The gut microbiota influences the reactivity of the immune system, and has emerged as an anti-inflammatory commensal. Here, we investigated whether its lysate could prevent severe forms of neuroinflammation in experimental autoimmune encephalomyelitis (EAE) in mice and how this preventive strategy affects the gut microbiota and immune response. Lysate of anaerobically cultured (Pd lysate) was orally administered to C57BL/6 mice in four weekly doses.

Hydrophobins are small amphiphilic proteins that confer filamentous fungal hydrophobicity needed for hyphal growth, development, dispersal and adhesion to host and substrata. In insect-pathogenic Beauveria bassiana, nine hydrophobins (class I Hyd1A-F and class II Hyd2A-C) were proven to localize on the cell walls of aerial hyphae and conidia but accumulate in the vacuoles and vesicles of submerged hyphae and blastospores, respectively. Conidial hydrophobicity, adhesion to insect cuticle, virulence via normal cuticle infection and dispersal potential were significantly more reduced by the hyd1A deletion leading to complete ablation of slender rodlets on conidial coat than the hyd1B deletion, which caused a failure to assemble morphologically irregular rodlets into orderly bundles.
