Shaping current European mitochondrial haplogroup frequency in response to infection: the case of SARS-CoV-2 severity.

The frequency of mitochondrial DNA haplogroups (mtDNA-HG) in humans is known to be shaped by migration and repopulation. Mounting evidence indicates that mtDNA-HG are not phenotypically neutral, and selection may contribute to its distribution. Haplogroup H, the most abundant in Europe, improved survival in sepsis.

Genomes of nine cultured microbes from two hydrologically connected freshwater sites in Wellesley, MA.

We present the genomes of nine cultured microbes isolated from two freshwater sites in Wellesley, MA. The dataset is useful for exploring genomic diversity among freshwater taxa, including , , , and .

Deriving Human Intestinal Organoids with Functional Tissue-Resident Macrophages All From Pluripotent Stem Cells.

Background & Aims: Organs of the gastrointestinal tract contain tissue-resident immune cells that function during tissue development, homeostasis, and disease. However, most published human organoid model systems lack resident immune cells, thus limiting their potential as disease avatars. For example, human intestinal organoids (HIOs) derived from pluripotent stem cells contain epithelial and various mesenchymal cell types but lack immune cells.

New York State Climate Impacts Assessment Chapter 04: Buildings.

New York State has nearly 5.3 million buildings, and all of them are vulnerable in some way to the impacts of climate change. Understanding these impacts is critical, because risks to buildings not only threaten individual lives but also pose threats to community-level resilience.

Graft-derived extracellular vesicles transport miRNAs to modulate macrophage polarization after heart transplantation.

Heart transplantation, a crucial intervention for saving lives of those with end-stage cardiac failure, often faces complications from acute allograft rejection. This study focuses on the intricate dynamics of immune cell interactions and specific communication pathways between organs, which are not yet well understood. Our study investigates this interplay using a murine heterotopic transplant model, using single-cell RNA sequencing to examine CD45 immune cells from both the heart grafts and spleens.
