In this study, we showed that the iPaD (inducing Plagl2 and anti-Dyrk1a) lentivirus substantially rejuvenated the proliferative and neurogenic potential of NSCs in the aged brain. Clonal analysis by a sparse labeling approach as well as transcriptome analysis indicated that iPaD can rejuvenate aged NSCs (19-21 mo of age) to a level comparable with those at 1 or 2 months of age and successfully improved cognition of aged mice.
Once rejuvenated and activated by iPaD, aged dormant NSCs can generate, on average, 4.9 neurons but very few astrocytes in 3-week tracing. Furthermore, these activated NSCs were maintained for ...

A Look Back at 2021: Progress Towards the Treatment of Aging as a Medical Condition
Well, here we are again, at the end of another pandemic year, a year older and - hopefully - a year wiser and more knowledgeable. I said all that really needs to be said on the topic of COVID-19 as an age-related condition at the end of last year. We might hope that, given widespread vaccination, the pandemic will become a topic of diminishing importance as the year ahead progresses, even given the present round of variants, fears, and reintroduction of restrictions.

We report that whereas microglia are characterized by marked gene-level alterations related to negative regulation of protein phosphorylation and phagocytic vesicles, astrocytes show activation of enzyme- or peptidase-inhibitor signaling after detectable changes in BBB permeability. We also identify several genes enriched in these pathways that are notably altered after BBB breakdown. Our data reveal that microglia and astrocytes play an active role in maintaining BBB stabilization and corralling infiltrating cells, and thus might potentially function in ameliorating the lesions and neurologic disabilities in CNS diseases....

In conclusion, the low dose, prolonged angiotensin II exposure is associated with the induction of senescence in kidneys and the promotion of an inflammatory microenvironment through both secreted factors and immune cells. Endothelial cells appear to be a major cell type impacted. The elimination of senescent cells in the INK-ATTAC transgenic model prevents these effects of angiotensin II and reveals a novel pathophysiologic mechanism amenable to targeting by senolytic drugs in development.

In this study, they found these drugs can kill senescent cells from cultures of human fat tissue. The tissue was donated by individuals with obesity who were known to have metabolic troubles. Without treatment, the human fat tissues induced metabolic problems in immune-deficient mice. After treatment with dasatinib and quercetin, the harmful effects of the fat tissue were almost eliminated.

The Lack of Funding for Chronic Kidney Disease Research is Not an Outlier
In this commentary, scientists note the paucity of funding for chronic kidney disease research, given the widespread suffering and death caused by this presently incurable condition. This and many other areas of medicine are seen as solved problems by the powers that be simply because there is some form of treatment, even palliative treatment, in widespread use. That the treatment does little and many people die doesn't appear to motivate those who could fund progress. There is no sense of urgency and little sense of need. We might make the same comments in the case of atherosclerosis, a condition many consider to be adequ...

Making first contact: What to do with all that information! part 2
Last week I described some of the reasons for using a case formulation approach when working through initial assessment information, and today I’m going to describe one approach for organising a formulation. This is the “4 P” formulation, and it’s one that’s often used in mental health (Bolton, 2014).
In the 4 P model, there are four questions to ask yourself:
Preconditions – Why is this person vulnerable to this problem?Precipitating factors – Why now? This can mean “why is this person having symptoms now?” or “why is this person presenting to this person ...

How advanced analytics can help social determinants of health
Health care costs in the U.S. have increased dramatically over the past five decades, from $74 billion in 1970 to $3.8 trillion in 2019. This trend has been fueled in large part by an increase in the number of people who struggle with chronic conditions such as cancer, diabetes, hypertension, and lung disease.

This study nicely illustrates the importance of the cellular metabolic state of myeloid cells: it highlights that not only the availability of glucose, but also its channeling into different pathways (glycolysis versus glycogen synthesis) contributes to maintaining proper myeloid function.

In conclusion, in less common and visible cardiovascular diseases, it is crucial to recognize substantial progress and achievement, given that penetration of such information into clinical practice and the patient community can be inconsistent. Diseases such as hypertrophic cardiomyopathy, pulmonary arterial hypertension, and ATTR cardiac amyloidosis, once linked to a uniformly adverse prognosis, are now associated with the opportunity for patients to experience satisfactory quality of life and extended longevity.

Reflections on HLTH2021: The Lens of the Patient and Carepartner
By GRACE CORDOVANO
Attending HLTH 2021 in-person in Boston solidified that there is no comparison between attending live vs. virtual conferences. While content and presentations can be solid both virtually or in-person, it is the energy of the connections that are made between scheduled presentations and the conversations that are shared throughout that move the needle. Kudos to the organizers of HLTH 2021 for prioritizing the safety of all in-person attendees with COVID-19 vaccination requirements, proof of negative PCR testing within 3 days of arrival, and mask requirements on-site.
After reflecting on all th...

In conclusion, mitophagy pathways play an important role in maintaining physiological homeostasis, are involved in the mechanisms of aging and neurodegenerative disorders, and represent promising targets for the development of potential therapeutic agents aimed at regulating mitochondria quality control in neurons and glial cells. A significant number of molecules that induce or inhibit mitophagy are currently under consideration, which may be useful for testing hypotheses or developing drugs for the treatment of neurodegenerative diseases. The validation of promising drugs in animal and cell models, including neurons and ...
