Wild red deer (Cervus elaphus) do not play a role as vectors or reservoirs of SARS-CoV-2 in north-eastern Poland.

The study tested 90 wild red deer in Poland for SARS-CoV-2 antibodies and viral RNA but found no evidence of infection, suggesting they are not reservoirs or vectors of the virus in this region.

Serological surveillance for wild rodent infection with SARS-CoV-2 in Europe

The paper reports serological testing of 1,237 wild rodents and other small mammals across Europe for SARS-CoV-2 exposure, finding all samples negative except one.

Zoonotic spillover of SARS-CoV-2: mink-adapted virus in humans

The paper reports the spillover of mink-adapted SARS-CoV-2 from farmed mink to humans, identifying specific mutations in the S gene.

Seroprevalence of Toxoplasma gondii among sylvatic rodents in Poland

The paper reports the seroprevalence of Toxoplasma gondii in four sylvatic rodent species in Poland, finding 5.5% overall with higher prevalence in some vole species.

Detection and molecular characterisation of SARS-CoV-2 in farmed mink (Neovision vision) in Poland

The paper detects and characterizes SARS-CoV-2 infection in farmed minks in Poland using RT-PCR, antigen detection, and NGS, confirming 15 positive cases and highlighting the risk of mink farms as potential sources of the virus.

Insight into glycosphingolipid crypticity: Crystal structure of the anti-tumor antibody 14F7 and recognition of NeuGc GM3 ganglioside

This paper presents the crystal structure of the 14F7 antibody bound to NeuGc GM3 and shows how membrane composition and curvature influence its binding.

Obesity-associated lipidomic remodeling of the adrenal gland indicates an important role of the FADS2-arachidonic acid axis in adrenocortical hormone production

This study identifies obesity-induced lipidomic changes in the adrenal gland, showing that the FADS2-arachidonic acid pathway regulates adrenocortical hormone production.

Zoonotic viruses in three species of voles (Microtus spp.) from Poland

The paper detects antibodies against cowpox virus and Puumala virus in three vole species in NE Poland, finding similar seroprevalence across species and no sex or age differences.

Purification of age-distinct insulin secretory granules through antigen restriction

The paper purifies age-distinct insulin secretory granules from INS-1 cells and identifies age-related changes in their lipid composition and membrane properties.

Selective phosphorylation of AKT isoforms in response to dietary cues

The paper identifies specific AKT isoforms that respond to dietary lipid extracts and enhance insulin signaling, positioning Drosophila as a model for studying lipid cue-insulin signaling relationships.

Comprehensive and quantitative analysis of white and brown adipose tissue by shotgun lipidomics

This paper presents a validated shotgun lipidomics method for adipose tissue, revealing diet-related lipidomic differences in brown, gonadal, and inguinal subcutaneous fat from lean and obese mice.

Visualization of ligand-induced transmembrane signalling in the full-length human insulin receptor

The paper visualizes how insulin binding changes the structure of the human insulin receptor, leading to autophosphorylation.

Detection Of Human Disease Conditions By Single-Cell Morpho-Rheological Phenotyping Of Whole Blood

This paper introduces a method to detect human disease conditions by analyzing whole blood using morpho-rheological phenotyping without labeling or separation.
