Mechanism Underlying Ganoderma lucidum Polysaccharide Biosynthesis Regulation by the β-1,3-Glucosyltransferase Gene gl20535

mycolabadmin

Researchers studied a gene called gl20535 in the medicinal mushroom Ganoderma lucidum that controls how the fungus makes beneficial polysaccharides. When they increased this gene’s activity, the mushroom produced significantly more polysaccharides with improved composition. The gene works by controlling sugar pathways and related enzyme production, and the mushroom compensates when this gene is reduced. These findings could help improve the production of medicinal mushroom products for food and health applications.

Experimental research on fungal inhibition using dissolving microneedles of terbinafine hydrochloride nanoemulsion for beta-1,3-glucanase

mycolabadmin

Researchers developed a new patch treatment for nail fungus using tiny dissolving needles that deliver antifungal medication directly into the skin near infected nails. The patch combines two active ingredients that work together to kill fungus and break down protective biofilm layers that make fungal infections hard to treat. Testing showed the patch was safe, effective, and delivered much more medication to the infected area compared to traditional creams or pills.

Functional analysis of a novel endo-β-1,6-glucanase MoGlu16 and its application in detecting cell wall β-1,6-glucan of Magnaporthe oryzae

mycolabadmin

Scientists discovered and studied a special enzyme called MoGlu16 from rice blast fungus that breaks down a key component of fungal cell walls called β-1,6-glucan. This enzyme can be used to visualize where this cell wall component is located in the fungus at different stages of its life cycle. When applied to fungus spores, the enzyme prevents them from sprouting and forming infection structures, making it a promising candidate for developing new ways to control rice blast disease.

Kre6-dependent β-1,6-glucan biosynthesis only occurs in the conidium of Aspergillus fumigatus

mycolabadmin

Researchers discovered that a specific sugar compound called β-1,6-glucan is found in the spore-like reproductive structures (conidia) of the fungus Aspergillus fumigatus but not in its growing filaments (mycelium). Using advanced nuclear magnetic resonance technology, they identified the KRE6 gene as responsible for making this sugar and found that removing this gene makes the fungus more vulnerable to certain chemicals that damage fungal cell walls.

Protein kinase A signaling regulates immune evasion by shaving and concealing fungal β-1,3-glucan

mycolabadmin

Candida albicans is a fungus that causes infections in humans. The fungus has developed a clever way to hide from our immune system by covering up a molecule on its surface called β-1,3-glucan that normally triggers immune responses. This study shows that the fungus masks this molecule through a combination of growing and dividing to create new surfaces, and then using enzymes to trim away exposed molecules. The research reveals that a specific cell signaling pathway controlled by lactate (a chemical found in our bodies) activates this masking behavior, helping the fungus evade immune recognition.
