COMMENT New work from the Wyss-Coray lab reports that CD22 plays a role in regulating the phagocytic capacity of microglia. This is a compelling paper that adds depth to our understanding of the intricate mechanisms that act to regulate microglial actions. CD22 ...
COMMENT Zhong and colleagues have recently reported a remarkable series of findings that demonstrate that soluble forms of TREM2 exhibit cell-autonomous actions and act to mitigate AD pathogenesis in mouse models of AD. These observations serve to focus attention ...
COMMENT Pan et al. report that oral administration of the flavonoid rutin to mouse models of Alzheimer’s disease results in amelioration of cognition deficits as well as a broad array of AD-related phenotypes. They report a dramatic reduction in plaque burden, an ...
COMMENT The congressional support for AD research in the recent past is extraordinary, and it is reassuring that our elected representatives have come to recognize the magnitude of the impact of the disease and provide new resources for research. The level of ...
COMMENT Liao et al. have reported that antibodies directed at human ApoE isoforms can reduce amyloid plaque burden in a mouse model of AD expressing human ApoE4. This study, like its predecessors from the Holtzman lab, derives from the recognition that plaques in ...
COMMENT The paper by Zhao and colleagues reports that Trem2 is a receptor for Aβ, joining a long list of cell surface Aβ-binding proteins on microglia. The authors argue that Trem2 preferentially interacts with Aβ oligomers, with Kd’s in the nM range. A point of ...
COMMENT The authors present an intriguing study that highlights the interplay between microglia and neurons in the progression of amyloid pathology in a mouse model of Alzheimer’s disease. Although others have demonstrated that early intervention with CSF1R ...
COMMENT There is now a substantial literature documenting the linkage of immune cell genes to neurodegenerative disease. This study validates the conclusion that microglia (and other myeloid subpopulations) contribute to risk for late-onset AD. Sims et al. have ...
COMMENT Zhong et al. report that soluble forms of TREM2 are able to elicit a robust proinflammatory response and promote survival in primary microglia. These findings provide a completely novel take on the biological roles of soluble TREM2. Previous work has ...
COMMENT The issue of reproducibility of preclinical studies is of substantial importance, and there is broad consensus that these types of investigation must be appropriately designed and powered. The current NIH–based effort to require rigorous experimental ...
COMMENT This is an interesting and thorough study, whose experimental outcomes are pretty clear. One question one could ask is why chronic treatment with the PTEN inhibitor is necessary to improve the behavioral outcomes. There is no change in pAKT in the chronic ...
COMMENT The additional funding for AD research is a very welcome, but long overdue, development for those of us in the research community. The new funding has generated considerable excitement over the prospect of deploying new tools and understanding to dissect ...
COMMENT This is a compelling study from the Tontonoz lab demonstrating the role of LDLR in amyloid pathogenesis in a mouse model of AD. This work follows directly from their discovery that Idol acts to promote the proteolytic degradation of LDLR through its ...
COMMENT This recent publication by Roy et al. reports a novel, non-canonical action of statins in the brain, whereby they stimulate the nuclear receptor PPARα. There has been considerable controversy over the pleiotrophic actions of the statins, in particular as ...
COMMENT There is considerable confusion over the roles of neuroinflammation in animal models of Alzheimer’s disease and other neurodegenerative disorders. The complementary studies of Chakrabarty et al. and Guillot-Sestier et al. have shed new light, but not ...
