The transmission bottleneck, defined as the number of viruses shed from one host to infect another, is an important determinant of the rate of virus evolution and the level of immunity required to protect against virus transmission. Despite its importance, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission bottleneck remains poorly characterized. We adapted a SARS-CoV-2 reverse genetics system to generate a pool of >200 isogenic SARS-CoV-2 viruses harboring specific 6-nucleotide barcodes, infected donor hamsters with this pool, and exposed contact hamsters to paired infected donors, varying the duration and route of exposure.

Bacterial-fungal interaction (BFI) has significant implications for the health of host plants. While the diffusible antibiotic metabolite-mediated competition in BFI has been extensively characterized, the impact of intercellular contact remains largely elusive. Here, we demonstrate that the intercellular contact is a prevalent mode of interaction between beneficial soil bacteria and pathogenic filamentous fungi.

Purpose: Stress granules (SGs) are cytoplasmic biocondensates formed in response to various cellular stressors, contributing to cell survival. Although implicated in diverse pathologies, their role in retinal degeneration (RD) remains unclear. We aimed to investigate SG formation in the retina and its induction by excessive LED light in an RD model.

Podocytes are essential to maintain the normal filtration function of glomerular basement membrane, which could be injured by ischemia-reperfusion. As complicated function of autophagy in terminal differentiated podocytes, autophagy dysfunction might contribute to I/R induced renal dysfunction following glomerular filtration membrane (GFM) injuries. Meanwhile, apelin-13, an endogenous polypeptide, has been proved to be effective in regulating autophagy and apoptosis in podocytes.

Background: Although mice are used extensively to study atherosclerosis of different vascular beds, limited data is published on the occurrence of intracranial atherosclerosis. Since intracranial atherosclerosis is a common cause of stroke and is associated with dementia, a relevant animal model is needed to study these diseases.
Methods And Results: We examined the presence of intracranial atherosclerosis in different atherogenic mouse strains and studied differences in vessel wall characteristics in mouse and human tissue in search for possible explanations for the different atherosclerotic susceptibility between extracranial and intracranial vessels.
