In conclusion, a number of studies have shown that CD4+ Treg cells are crucial in the maintenance of peripheral tolerance and have an important role in the control of atherosclerosis-related inflammation. Therefore, Treg cells are a promising target of major research efforts focused on immune-modulating therapies against atherosclerosis. Developing anti-atherosclerotic Treg-based therapies faces challenges. However, rapid progress in genetic, epigenetic, and molecular aspects of cellular immunology gives hope for a fast-track solution.

Pigs as a Model to Explore Links Between the Gut Microbiome and Chronic Inflammation in Aging
This study employed a comprehensive metagenomic analysis encompassing saliva and stool samples obtained from 45 pigs representing three distinct age groups, alongside serum metabolomics and lipidomics profiling. Our findings unveiled discernible modifications in the gut and oral microbiomes, serum metabolome, and lipidome at each age stage. Specifically, we identified 87 microbial species in stool samples and 68 in saliva samples that demonstrated significant age-related changes. Notably, 13 species in stool, including Clostridiales bacterium, Lactobacillus johnsonii, and Oscillibacter spp., exhibited age-dependent alterat...

In conclusion, here, we demonstrate a novel mechanism for ESC-EVs to protect cells from senescence. However, whether ESC-EVs rejuvenate aged mice via miR-15b-5p and miR-290a-5p remains unknown. Next, we plan to use miR-15b-5p and miR-290a-5p antagonists while treating aged mice with ESC-EVs to further investigate the mechanism by which ESC-EVs resist aging in vivo.

Hoping for Gut Microbiome Rejuvenation to Reduce the Incidence of Alzheimer's Disease
It has only comparatively recently become widely understood that the microbial populations making up the gut microbiome change in abundance in characteristic ways with age. Similarly, that the gut microbiome tends to be different in characteristic ways in older people who go on to develop Alzheimer's disease. It remains to be seen as to whether an altered gut microbiome is a meaningful contributing cause to Alzheimer's disease, such as via increased chronic inflammation, or a side effect of some other meaningful contribution, such as the aging of the immune system. At the least, it presents a novel way to assess risk in ol...

In this study, we tested the hypothesis that periodontal disease (PD) as a source of infection alters inflammatory activation and Aβ phagocytosis by the microglial cells.
Experimental PD was induced using ligatures in C57BL/6 mice for 1, 10, 20, and 30 days to assess the progression of PD. Animals without ligatures were used as controls. Ligature placement caused progressive periodontal disease and bone resorption that was already significant on day 1 post-ligation and continued to increase until day 30. The severity of periodontal disease increased the frequency of activated microglia in the brains on day 30 by 36...

The Presence of Streptococcus Species in the Gut Microbiome Correlates with Atherosclerotic Plaque Burden
It is presently possible to cheaply and reliably determine the bacterial populations making up the gut microbiome via 16S rRNA sequencing. This capability is giving rise to great deal of new knowledge regarding the ways in which changes in the gut microbiome affect health. Populations can provoke inflammation, known to drive the onset and progression of many age-related conditions, or generate harmful or helpful metabolites, about which less is known of the interaction with specific aspects of aging. Adjusting the balance of populations in the gut microbiome, particularly to restore a more youthful gut microbiome in older ...

Yoghurt: A Delicious Solution To High Blood Pressure?
Conclusion
In a nutshell, the humble pot of yoghurt could be a powerful tool in the fight against high blood pressure.
From its impressive mineral content to the potential blood-pressure-lowering action of its amino acids, yoghurt has proven to be more than just a tasty snack.
However, as we’ve learned from Dr. Lee, the type and quantity of yoghurt we consume matters.
The takeaway?
Dietary choices can significantly impact our health, making conscious consumption essential.
Now, you might view that bowl of yoghurt in a new light, not only for its delicious taste but also for its potential health-...

In this study, cultured adipose-derived stem cells (ASCs) were derived from subcutaneous white adipose tissue isolated from mice fed a normal diet. We performed senescence-associated-β-galactosidase (SA-β-gal) staining, real-time PCR, and Western blot to evaluate the levels related to cellular senescence markers.
The mRNA expression levels of senescence markers were significantly increased in the later passages of ASCs. We show that light activation reduced the expression of senescent genes, and SA-β-Gal in all cells at passages. Moreover, the light-activated ASCs-derived exosomes decrease the expression of senes...

If Probiotics in their Present Form Were a Truly Effective Intervention, We Would Already Know
There is an increasing focus in the research community on the role of the gut microbiome in aging. This is in large part driven by the ability to accurately, cost-effectively measure the composition of the gut microbiome from a stool sample, using 16S rRNA sequencing. The 16S rRNA gene is differs between bacterial species, without being subject to a high rate of mutation and change. Using low-cost modern techniques, researchers can thus read out the relative numbers of different species in the gut microbiome, a service now available to the public at large as well. This allows researchers to see exactly how the balance of p...

Shelf-Stable Breast Milk Powder: Interview with Dr. Vansh Langer, CEO at BBy
BBy, a medtech company based in New York, has developed a spray drying method that hospitals can use to process human breast milk into a shelf-stable powder. Human breast milk is an incredibly important source of nutrition for neonates in intensive care units (NICUs). At present, human donor milk is frozen and must be defrosted prior to use in such facilities. This is highly labor intensive for staff and is very wasteful, as excess defrosted milk must be thrown away and large freezers use a lot of electricity.
The spray drying technology developed by BBy converts human breast milk into a shelf-stable dry powder that can...

In this study, we investigated the effect of NXP032 on neurovascular stabilization through the changes of PECAM-1, PDGFR-β, ZO-1, laminin, and glial cells involved in maintaining the integrity of the blood-brain barrier (BBB) in aged mice. NXP032 was orally administered daily for 8 weeks. Compared to young mice and NXP032-treated mice, 20-month-old mice displayed cognitive impairments in Y-maze and passive avoidance tests. NXP032 treatment contributed to reducing the BBB damage by attenuating the fragmentation of microvessels and reducing PDGFR-β, ZO-1, and laminin expression, thereby mitigating astrocytes and microglia ...
