Impact of Fire and Heat Stress on Soil Microorganisms: A Review of Community Changes, Molecular Responses and Plant‐Beneficial Roles

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, Volume 600, Issue 5, Page 591-611, March 2026.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Targeting Microglial CD49a Inhibits Neuroinflammation and Demonstrates Therapeutic Potential for Parkinson's Disease

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This study shows that integrin receptor CD49a (Itga1 gene) is significantly upregulated in hyperactivated microglia and microglia‐specific knockdown of Itga1 rescues neuroinflammation and neurodegeneration in a chronic Parkinson's disease (PD) model by targeting PGAM5‐mediated mitochondrial dysfunction and NLRP3 activation. Targeted inhibition of CD49a

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

Food Frontiers, Volume 7, Issue 2, March 2026.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.

Free living amoebae and human disease

Microbiology Australia, 2016
Pathogenic FLA are ubiquitous protozoans and despite frequent human contact remain a rare cause of often devastating infectionwith poor prognosis. Given changes in climate, human encroachment into the environment, increasing immunosuppression, and improving diagnostic capacity, it is likely we will see increased cases in the future.
