Analysis of adaptation mutants in the hemagglutinin of the influenza A(H1N1)pdm09 virus. [PDF]
Hemagglutinin is the major surface glycoprotein of influenza viruses. It participates in the initial steps of viral infection through receptor binding and membrane fusion events.

Immunodominant surface epitopes power immune evasion in the African trypanosome
Summary: The African trypanosome survives the immune response of its mammalian host by antigenic variation of its major surface antigen (the variant surface glycoprotein or VSG). Here we describe the antibody repertoires elicited by different VSGs.

Identification and functional characterization of a highly divergent N-acetylglucosaminyltransferase I (TbGnTI) in Trypanosoma brucei [PDF]
Trypanosoma brucei expresses a diverse repertoire of N-glycans, ranging from oligomannose and paucimannose structures to exceptionally large complex N-glycans.

The V5A13.1 envelope glycoprotein deletion mutant of mouse hepatitis virus type-4 is neuroattenuated by its reduced rate of spread in the central nervous system. [PDF]
Following intracerebral inoculation of adult Balb/c Byj mice, the MHV-4 strain of mouse hepatitis virus (MHV) had an LD50 of less than 0.1 PFU, whereas its monoclonal antibody resistant variant V5A13.1 had an LD50 of 10(4.2) PFU.

The trypanosomal transferrin receptor of trypanosoma brucei : a review [PDF]
Iron is an essential element for life. Its uptake and utility requires a careful balancing with its toxic capacity, with mammals evolving a safe and bio-viable means of its transport and storage. This transport and storage is also utilized as part of the

How molecular crowding affects membrane protein diffusion and function is not known. Here the authors measure diffusion of variant surface glycoprotein on trypanosomes and discover a molecular crowding threshold that limits diffusion, and find that N ...

Escaping the immune system by DNA repair and recombination in African trypanosomes [PDF]
African trypanosomes escape the mammalian immune response by antigenic variation—the periodic exchange of one surface coat protein, in Trypanosoma brucei the variant surface glycoprotein (VSG), for an immunologically distinct one.

Monoclonal anti-envelope antibody AP33 protects humanized mice against a patient-derived hepatitis C virus challenge [PDF]
End-stage liver disease caused by hepatitis C virus (HCV) infection is a major indication for liver transplantation. However, immediately after transplantation the liver graft of viremic patients universally becomes infected by circulating virus ...

Pedal to the Metal: Nuclear Splicing Bodies Turbo-Charge VSG mRNA Production in African Trypanosomes
The African trypanosome Trypanosoma brucei is a parasite of the mammalian bloodstream and tissues, where an antigenically variable Variant Surface Glycoprotein (VSG) coat protects it from immune attack.

Mutational sensitivity of D614G in spike protein of SARS-CoV-2 in Jordan
Background: Spike protein is the surface glycoprotein of the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) necessary for the entry of the virus via the transmembrane receptors of the human respiratory cells causing COVID-19 disease.
