Mitochondrial DNA in Mitochondrial Dysfunction
Reading Time: 5 minutesMitochondria carry their own DNA. As mtDNA damage accumulates, leaked mtDNA acts as a DAMP, hyper-activates the innate immune system, and feeds the senescence-inflammation loop. New therapeutics target the cGAS-STING and NLRP3 pathways to break the cycle.

Metabolic Reprogramming of Immune Senescence
Reading Time: 5 minutesImmunocompetence declines with age as immune cell metabolism becomes less adaptive. Spermidine, NAD+, senolytics, and emerging nanoparticle-based delivery systems may restore immunometabolic health and reverse age-associated senescence.

Three Distinct Probiotics
Reading Time: 5 minutesEach strain in a probiotic exerts a specific effect on the microbiome. A recent study compared three formulations — and found that combining more strains doesn’t always mean greater impact on diversity, bile acids, or SCFA production.

Dysbiosis Post Brain Injury
Reading Time: 4 minutesAcute brain injury destabilizes the gut microbiome, shifting toward pro-inflammatory species and disrupting metabolites. A leaky intestinal barrier feeds back through the gut-brain axis to compound neurological damage.

Gut Motility – Not Just Regularity
Reading Time: 3 minutesGut motility is the axis of host-microbe coevolution. Peristalsis, segmentation, and migrating motor complexes shape microbial composition, nutrient absorption, and bidirectional gut-brain signaling.

Copper and Osteoporosis
Reading Time: 2 minutesCopper is a critical trace element implicated in bone metabolism. Low dietary and circulating copper levels link with osteoporosis incidence — but a U-shaped dose-response means more isn’t always better.

High Load for the (Immune) Win
Reading Time: 5 minutesMenopause impairs T lymphocyte function. High-load resistance training generates greater mechanical stress, upregulates HSPB1 expression, and mobilizes anti-inflammatory CD4+ T cells.

Understanding Blood-Flow Restriction Training
Reading Time: 8 minutesI started hearing about blood flow restriction training several years ago, but never really gave it much credence. I thought it was mostly a gimmick to give people that sought-after ‘pump’ which isn’t actually a useful marker of efficacy. I have begun to see blood-flow restriction being implemented more and more frequently…

Autophagy: Taming the Beast
Reading Time: 12 minutesBe sure to check out An Introduction to Autophagy, Autophagy: When, What, Where, and Why, and Autophagy: When Things Go Wrong. Congratulations! You’ve made it to the fun part. Now we get to discuss how we might harness autophagy to our (healthspan) advantage. As a quick debrief, autophagy is a form of…
