A probabilistic histological atlas of the human brain for MRI segmentation

2 weeks 5 days ago
In human neuroimaging, brain atlases are essential for segmenting regions of interest (ROIs) and comparing subjects in a common coordinate frame. State-of-the-art atlases derived from histology^(1-3) provide exquisite three-dimensional cytoarchitectural maps but lack probabilistic labels throughout the whole brain: that is, the likelihood of each location belonging to a given ROI. Here we present NextBrain, a probabilistic histological atlas of the whole human brain. We developed artificial...

Lymphoid gene expression supports neuroprotective microglia function

2 weeks 5 days ago
Microglia, the innate immune cells of the brain, play a defining role in the progression of Alzheimer's disease (AD)¹. The microglial response to amyloid plaques in AD can range from neuroprotective to neurotoxic². Here we show that the protective function of microglia is governed by the transcription factor PU.1, which becomes downregulated following microglial contact with plaques. Lowering PU.1 expression in microglia reduces the severity of amyloid disease pathology in mice and is linked to...

Hippocampal 1H-MR spectroscopy metabolites are linked to CSF tau pathology in cognitively unimpaired older adults along the Alzheimer's continuum

2 weeks 5 days ago
Relationships between Alzheimer's disease (AD) pathologies in cognitively unimpaired adults and in vivo neurometabolic properties measured directly from the hippocampus, a vulnerable region early along the AD continuum, are not well-understood in the earliest stages of AD. In a 3T ¹H-MRS study, we assessed age and AD-related changes in estimates of absolute concentrations of neurometabolites in the right hippocampus. Participants included older adults (age range: 60-85, n = 19) primarily...

Long-lived IgE plasma cells persist in secondary lymphoid tissues using a navitoclax-sensitive survival program

2 weeks 5 days ago
Long-term allergies can exhibit persistent concentrations of circulating immunoglobulin E (IgE). Here, we examined the lifespan of IgE antibody-secreting cells (ASCs) to determine whether the IgE that sustains allergies receives contributions from long-lived cells or relies more heavily on constant ASC production. In mouse aeroallergy, IgE ASCs localized to the lungs, mediastinal lymph nodes, spleen, and bone marrow (BM). IgE ASC production continued for months after allergen exposure ceased. We...
