Relative Roles of GM1 Ganglioside, N-Acylneuraminic Acids, and 2 1 Integrin in Mediating Rotavirus Infection

Relative roles of GM1 ganglioside, N-acylneuraminic acids, and α2β1 integrin in mediating rotavirus infection.

UNLABELLED N-acetyl- and N-glycolylneuraminic acids (Sia) and α2β1 integrin are frequently used by rotaviruses as cellular receptors through recognition by virion spike protein VP4. The VP4 subunit VP8*, derived from Wa rotavirus, binds the internal N-acetylneuraminic acid on ganglioside GM1. Wa infection is increased by enhanced internal Sia access following terminal Sia removal from main glyc...

Increased cerebrospinal fluid ganglioside GM1 concentrations indicating neuronal involvement in all stages of HIV-1 infection.

UNLABELLED Measurements of cerebrospinal fluid (CSF) concentrations of gangliosides can be used as markers of central nervous system (CNS) neuronal involvement. We have analysed the CSF concentrations of the four major brain gangliosides GM1, GD1a, GD1b, and GT1b at different stages of HIV-1 infection. CSF samples were collected from 44 HIV-1-infected patients and from 24 HIV-negative, healthy ...

Trial of ganglioside GM1 in acute stroke.

Ganglioside GM1 (100 mg) was given daily by intramuscular injection for 28 days in a double-blind placebo controlled trial of acute stroke. No significant difference was detected in a 6 month follow-up period between well matched control and active groups. Although the number of patients studied was small the findings are believed to indicate that GM1 is unlikely to be of value in the treatment...

GM1 ganglioside therapy in acute ischemic stroke.

The presence of Mycoplasma pneumoniae infection and GM1 ganglioside antibodies in Guillain-Barré syndrome.

INTRODUCTION Guillain-Barré syndrome (GBS) is an autoimmune disorder affecting the peripheral nervous system, usually triggered by an acute infection. GBS patients are known to have antecedent bacterial infections associated with auto-antibodies to various gangliosides. This investigation aimed to evaluate GBS patients for serological evidence of Mycoplasma pneumoniae infection and anti GM1 gan...
