Screening coronavirus and human proteins for sialic acid binding sites using a docking approach
AIMS Biophysics, 2021 The initial step of interaction of some pathogens with the host is driven by the interaction of glycoproteins of either side via endcaps of their glycans. These end caps consist of sialic acids or sugar molecules.

Unraveling the Differences of the Hydrolytic Activity of Trypanosoma cruzi trans-Sialidase and Trypanosoma rangeli Sialidase: A Quantum Mechanics–Molecular Mechanics Modeling Study [PDF]
, 2014 Chagas’ disease, also known as American trypanosomiasis, is a lethal, chronic disease that currently affects more than 10 million people in Central and South America. The trans-sialidase from Trypanosoma cruzi (T. cruzi, TcTS) is a crucial enzyme for the

Distinct Roles for Sialoside and Protein Receptors in Coronavirus Infection
mBio, 2020 Coronaviruses (CoVs) are common human and animal pathogens that can transmit zoonotically and cause severe respiratory disease syndromes. CoV infection requires spike proteins, which bind viruses to host cell receptors and catalyze virus-cell membrane ...

Influence of Host Sialic Acid Receptors Structure on the Host Specificity of Influenza Viruses
Viruses, 2022 Influenza viruses need to use sialic acid receptors to invade host cells, and the α-2,3 and α-2,6 sialic acids glycosidic bonds linking the terminal sialic acids are generally considered to be the most important factors influencing the cross-species ...

Siglecs facilitate HIV-1 infection of macrophages through adhesion with viral sialic acids. [PDF]
PLoS ONE, 2011 Human immunodeficiency virus type 1 (HIV-1) infects macrophages effectively, despite relatively low levels of cell surface-expressed CD4. Although HIV-1 infections are defined by viral tropisms according to chemokine receptor usage (R5 and X4 ...

Infection-generated electric field in gut epithelium drives bidirectional migration of macrophages. [PDF]
, 2019 Many bacterial pathogens hijack macrophages to egress from the port of entry to the lymphatic drainage and/or bloodstream, causing dissemination of life-threatening infections. However, the underlying mechanisms are not well understood.
