Antigen-specific age-related memory CD8 T cells induce and track Alzheimer’s-like neurodegeneration
This study changes our view of Alzheimer’s disease (AD) initiation and progression. Mutations promoting cerebral beta-amyloid (Aβ) deposition guarantee rare genetic forms of AD. Thus, the prevailing hypothesis has been that Aβ is central to initiation and progression of all AD, despite contrary animal and…
Evolutionary Selection of APOEɛ4 Encourages Increased Focus on Immunity in Alzheimer’s Disease
Smith and Ashford present a compelling hypothesis on evolution of APOE alleles, namely that ɛ4 prevalence is mediated by immune selection pressure against enteric pathogens. While the ɛ3 allele is more prevalent today, it outcompetedɛ4 only relatively recently, as immune selection pressure for more effective…
Glioma immunotherapy enhancement and CD8-specific sialic acid cleavage by isocitrate dehydrogenase (IDH)-1
The promise of adaptive cancer immunotherapy in treating highly malignant tumors such as glioblastoma multiforme (GBM) can only be realized through expanding its benefits to more patients. Alleviating various modes of immune suppression has so far failed to achieve such expansion, but exploiting endogenous immune…
CD103 Deficiency Promotes Autism (ASD) and Attention-Deficit Hyperactivity Disorder (ADHD) Behavioral Spectra and Reduces Age-Related Cognitive Decline
The incidence of autism spectrum disorders (ASD) and attention deficit hyperactivity disorder (ADHD), which frequently co-occur, are both rising. The causes of ASD and ADHD remain elusive, even as both appear to involve perturbation of the gut-brain-immune axis. CD103 is an integrin and E-cadherin receptor…
Functional recreation of age-related CD8 T cells in young mice identifies drivers of aging- and human-specific tissue pathology
Congrats to the whole T-Neuro team, and especially Chris Wheeler on our recent publication! This is a significant step forward in understanding how s specific immune change leads to disorders of aging throughout the body. The work introduces a unique research tool to examine how…
