Background: The previously underestimated effects of commensal gut microbiota on the human body are increasingly being investigated using omics. The discovery of active molecules of interaction between the microbiota and the host may be an important step towards elucidating the mechanisms of symbiosis.
Results: Here, we show that in the bloodstream of healthy people, there are over 900 peptides that are fragments of proteins from microorganisms which naturally inhabit human biotopes, including the intestinal microbiota.
A T cell receptor (TCR) consists of α- and β-chains. Accumulating evidence suggests that some TCRs possess chain centricity, i.e.

The SER forms immature chylomicrons (iChMs) in the ER lumen. iChMs are delivered at the Golgi complex (GC) where they are subjected to additional glycosylation resulting in maturation of iChMs.

- A study involving 5,340 residents of Moscow investigated the relationship between immune responses (antibodies and T cells) to SARS-CoV-2 and the likelihood of COVID-19 infection.* -
- Results showed that individuals with both high T-cell and antibody responses had the lowest risk of infection, while those with only an antibody response also had a strong protective effect.* -
- The findings highlight that antibody responses are more crucial for protection against SARS-CoV-2 compared to T-cell responses, suggesting potential implications for public health policies related to COVID-19.*
Transaortic approach represents an alternative variant of transcatheter aortic valve implantation (TAVI) which combines benefits of antegrade transapical approach and high safety profile characteristic of transfemoral approach. This method has substantial advantages over subclavian and transapical approaches in cases of pronounced myocardial hypertrophy, left ventricular dysfunction, thinning of left ventricular wall. We describe here a hybrid intervention with simultaneous coronary artery bypass grafting and TAVI in a patient from high surgical risk group with multivessel coronary artery involvement and critical aortic stenosis.
