The Evolving Modern Management of Brain Metastasis.

The Evolving Modern Management of Brain Metastasis. Clin Cancer Res. 2019 Jun 18;: Authors: Fecci PE, Champion CD, Hoj J, McKernan C, Goodwin CR, Kirkpatrick J, Anders CK, Pendergast AM, Sampson JH Abstract The incidence of brain metastases is increasing as cancer therapies improve and patients live longer, providing new challenges to the multidisciplinary teams that care for these patients. Brain metastatic cancer cells possess unique characteristics that allow them to penetrate the blood brain barrier, colonize the brain parenchyma, and persist in the intracranial environment. Additionally, brain metastases subvert the innate and adaptive immune system, permitting evasion of the anti-tumor immune response. Better understanding of the above mechanisms will allow for development and delivery of more effective therapies for brain metastases. In this review, we outline the molecular mechanisms underlying development, survival, and immunosuppression of brain metastases. We also discuss current and emerging treatment strategies, including surgery, radiation, disease-specific and mutation-targeted systemic therapy, and immunotherapy.

We report that electrical stimulation (ES) stimulation of post-stroke aged rats led to an improved functional recovery of spatial long-term memory (T-maze), but not on the rotating pole or the inclined plane, both tests requiring complex sensorimotor skills. Surprisingly, ES had a detrimental effect on the asymmetric sensorimotor deficit. Histologically, there was a robust increase in the number of doublecortin-positive cells in the dentate gyrus and SVZ of the infarcted hemisphere and the presence of a considerable number of neurons expressing tubulin beta III in the infarcted area. Among the genes that were unique...

It remains the case that far too much of the extensively funded work on cancer therapies is only relevant to a tiny subset of cancers. This is no way to achieve success in the fight to control cancer: there is only so much funding, only so many researchers, and too many types of cancer for an incremental strategy to make earnest process over the next few decades. The important lines of research into cancer treatments are those that can in principle be applied to many (or preferably all) cancers, and that are in principle highly effective, such as inhibition of telomere lengthening. The ideal cancer therapy is one that can ...

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...

Current standard of care includes radiation, chemotherapy and surgical resection. Today, survival rates for malignant glioma patients remain dismal and unchanged for decades. The glioma microenvironment is highly immunosuppressive and consequently this has motivated the development of immunotherapies for counte...

This study delves into the mechanisms by which a short period of fasting can accelerate wound healing. Fasting triggers many of the same cellular stress responses, such as upregulated autophagy, as occur during the practice of calorie restriction. It isn't exactly the same, however, so it is always worth asking whether any specific biochemistry observed in either case does in fact occur in both situations. In particular, the period of refeeding following fasting appears to have beneficial effects that are distinct from those that occur while food is restricted. Multiple forms of therapeutic fasting have been repor...

In conclusion, taller body height at the entry to adulthood, supposed to be a marker of early-life environment, is associated with lower risk of dementia diagnosis later in life. The association persisted when adjusted for educational level and intelligence test scores in young adulthood, suggesting that height is not just acting as an indicator of cognitive reserve.

ConclusionThese results demonstrate that arginase is a key mediator of immuno suppression in gliomas, and inhibiting Arg1 shifts the immune response toward a pro-inflammatory environment. Our results suggest that combining OAT-1746 with other immunotherapies may improve responses in glioblastoma.Legal entity responsible for the studyMolecular Neurobiology, Nencki Institute of Experimental Biology.FundingProject DIMUNO: “Development of new cancer therapies based on selective antitumour immunomodulators”, co-financed by the National Centre for Research and Development.DisclosureAll authors have declared no conflicts of interest.
