High-fat diet increases circulating palmitic acid produced by gut Bacteroides thetaiotaomicron to promote thrombosis.

Circulating palmitic acid (PA) is generally considered to be provided from diets and endogenous synthesis and is adversely correlated with cardiovascular disease (CVD). It is unknown, however, if gut microbiota modulates circulating PA and potentiates CVD risk. Here we demonstrate that, in CVD patients, elevated circulating PA is accompanied with hypercoagulability and high gut Bacteroides thetaiotaomicron (BT) abundance.

Transferrin Disassociates TCR from CD3 Signaling Apparatus to Promote Metastasis.

Immune recognition and activation by the peptide-laden major histocompatibility complex-T cell receptor (TCR)-CD3 complex is essential for anti-tumor immunity. Tumors may escape immune surveillance by dissembling the complex. Here, we report that transferrin, which is overexpressed in patients with liver metastasis, disassociates TCR from the CD3 signaling apparatus by targeting the constant domain (CD) of T cell receptor α (TCRα), consequently suppresses T cell activation, and inhibits anti-metastatic and anti-tumor immunity.

Human transferrin receptor can mediate SARS-CoV-2 infection.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been detected in almost all organs of coronavirus disease-19 patients, although some organs do not express angiotensin-converting enzyme-2 (ACE2), a known receptor of SARS-CoV-2, implying the presence of alternative receptors and/or co-receptors. Here, we show that the ubiquitously distributed human transferrin receptor (TfR), which binds to diferric transferrin to traffic between membrane and endosome for the iron delivery cycle, can ACE2-independently mediate SARS-CoV-2 infection. Human, not mouse TfR, interacts with Spike protein with a high affinity (K ~2.
