Impaired immune response and barrier function in GSPD-1-deficient C. elegans infected with Klebsiella pneumoniae
Abstract gspd-1 -RNAi knockdown Caenorhabditis elegans was used as an immune-compromised model to investigate the role of G6PD in host-pathogen interactions. A shorted lifespan, increased bacterial burden and bacterial translocation were observed in gspd-1 -knockdown C. elegans infected with Klebsiella pneumoniae (KP). RNAseq revealed that the innate immune pathway, including clc-1 and tsp-1 , was affected by gspd-1 knockdown. qPCR confirmed that tight junction (zoo-1, clc-1 ) and immune-associated genes ( tsp-1 ) were down-regulated in gspd-1 -knockdown C. elegans and following infection with KP. The down-regulation of antimicrobial effector lysozymes, including lys-1, lys-2, lys-7, lys-8, ilys-2 and ilys-3 , was found in gspd-1 -knockdown C. elegans infected with KP. Deletion of clc-1, tsp-1, lys-7 , and daf-2 in...
The Human Microbiome Might Be Contagious
The largest & most diverse review to date has found evidence that who you live with & who you were raised by could have a greater impact on your microbiome than some lifestyle factors, age, or even genetics.
New study finds 6 ways to slow memory decline and lower dementia risk
A new study of more than 29,000 older adults has identified six habits — from eating a variety of foods to regularly reading or playing cards — that are linked with a lower risk of dementia and a slower rate of memory decline.
Influence of electromagnetic fields on the circadian rhythm: Implications for human health and disease
• The earth’s natural electromagnetic fields influence the circadian rhythm in humans. • Sunspots and seasonal weakening of the geomagnetic field can affect human health. • Seasonal geomagnetic field weakening increases infectious and chronic diseases. • Electromagnetic pollution from wireless devices can also affect circadian rhythms. • Grounding and reduction of electromagnetic pollution can produce health benefits.
How our microbiome is shaped by family, friends and even neighbors
People living in same household or in regular contact tend to have same microbes in their guts & mouths. The study raises possibility that diseases linked to microbiome dysfunction, including cancer , diabetes & obesity , could be partly transmissible.
