Cognitive deficits are a common comorbidity with neurological disorders and normal aging. Inflammation is associated with multiple diseases including classical neurodegenerative dementias such as Alzheimer's disease (AD) and autoimmune disorders such as multiple sclerosis (MS), in which over half of all patients experience some form of cognitive deficits. Other degenerative diseases of the central nervous system (CNS) including frontotemporal lobe dementia (FTLD), and Parkinson's disease (PD) as well as traumatic brain injury (TBI) and psychological disorders like major depressive disorder (MDD), and even normal aging all have cytokine-associated reductions in cognitive function.

Intravenously (IV) delivered BCG provides superior tuberculosis (TB) protection compared with the intradermal (ID) route in non-human primates (NHPs). We examined how γδ T cell responses changed in vivo after IV BCG vaccination of NHPs, and whether these correlated with protection against aerosol challenge. In the circulation, Vδ2 T cell populations expanded after IV BCG vaccination, from a median of 1.

Childhood poverty is the most widespread and important modifiable risk factor for the development of a range of health outcomes, including childhood-onset mental health problems. In the United States, 30 million children are growing up impoverished, which ranks among the highest per capita rates of child poverty among high-income countries. As a nation, the United States does less to support its poor children and their families than any other wealthy country, despite scientific evidence that growing up in poverty significantly increases lifetime risk of physical and mental health problems, reduces likelihood of academic and vocational success, and leads to poorer social outcomes for children.

Background: Schizophrenia (SCZ) is marked by working memory (WM) deficits, which predict poor functional outcome. While most functional magnetic resonance imaging studies of WM in SCZ have focused on the dorsolateral prefrontal cortex (PFC), some recent work suggests that the medial PFC (mPFC) may play a role. We investigated whether task-evoked mPFC deactivation is associated with WM performance and whether it mediates deficits in SCZ.

Tissue-resident memory T (T ) cells play a central role in immune responses to pathogens across all barrier tissues after infection. However, the underlying mechanisms that drive T differentiation and priming for their recall effector function remains unclear. In this study, we leveraged both newly generated and publicly available single-cell RNA-sequencing (scRNAseq) data generated across 10 developmental time points to define features of CD8 T across both skin and small-intestine intraepithelial lymphocytes (siIEL).

The function of the glomerulus depends on the complex cell-cell/matrix interactions and replication of this in vitro would aid biological understanding in both health and disease. Previous models do not fully reflect all cell types and interactions present as they overlook mesangial cells within their 3D matrix. Herein, the development of a microphysiological system that contains all resident renal cell types in an anatomically relevant manner is presented.

Examining intact kidney stones both qualitatively and quantitatively can be difficult due to their size and fragility. Many modern analysis methods often lead to the destruction of the stone's structure during sample preparation. Preserving the structural integrity is crucial for accurately determining the chemical distribution of the components of kidney stones, which, in turn, improves our understanding of the disease's etiology.
