Mucosal surfaces--such as the lining of the gut or the reproductive tract--are the main point of entry for viruses into the body. As such, almost all viruses interact with epithelial cells, and make use of the normal epithelial signalling and trafficking pathways of the host cell. In addition to protein receptors, carbohydrate chains of proteoglycans and epithelial-membrane glycosphingolipids have emerged as a new class of receptors for viral attachment to the host cell.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a respiratory virus that emerged in late 2019 and rapidly spread worldwide, causing the COVID-19 pandemic. The spike glycoprotein (S protein) plays a crucial role in viral target recognition and entry by interacting with angiotensin, converting enzyme 2 (ACE2), the functional receptor for the virus, via its receptor binding domain (RBD). The RBD availability for this interaction can be influenced by external factors, such as fatty acids.

Background And Aims: Bulevirtide (BLV) 2 mg/day is EMA approved for treatment of compensated chronic hepatitis due to Delta virus (HDV) infection, however real-life data in large cohorts of patients with cirrhosis are lacking.
Methods: Consecutive HDV-infected patients with cirrhosis starting BLV 2 mg/day since September 2019 were included in a European retrospective multicenter real-life study (SAVE-D). Patient characteristics before and during BLV treatment were collected.

Borna disease, which is a severe encephalitis that primarily affects horses and sheep, has been recognised for over two centuries. Borna disease virus 1 (BoDV-1) has been identified as a cause of a predominantly fatal encephalitis in humans. Little scientific data exist regarding the virus' transmission, entry portal, and excretion routes.

Pseudorabies virus (PRV) is one of the highly contagious pathogens causing significant economic losses to the swine industry worldwide. More importantly, PRV is becoming a potential "life-threatening zoonosis" since the human-originated PRV strain was first isolated in 2019. Previously we found that the canonical Wnt/β-catenin pathway facilitates PRV proliferation, while the underlying mechanism remains unknown.

Paramyxoviruses are significant human and animal pathogens that include mumps virus (MuV), Newcastle disease virus (NDV) and the murine parainfluenza virus Sendai (SeV). Despite their importance, few host factors implicated in paramyxovirus infection are known. Using a recombinant SeV expressing destabilized eGFP (rSeVCdseGFP) in a loss-of-function CRISPR screen, we identified the CMP-sialic acid transporter (CST) gene SLC35A1 and the UDP-galactose transporter (UGT) gene SLC35A2 as essential for paramyxovirus infection.
