Human PBMCs Form Lipid Droplets in Response to Spike Proteins

Florian Maria Wurm, Guillaume Raussin

Intracellular lipid droplets (LDs) can accumulate in response to inflammation, metabolic stresses, and other physiological/pathological processes. Herein, we investigated whether spike proteins of SARS-CoV-2 induce LDs in human peripheral blood mononuclear ...

Glycan heterogeneity as a cause of the persistent fraction in HIV-1 neutralization

Philippe Colin, Aleksandar Antanasijevic

Neutralizing antibodies (NAbs) to multiple epitopes on the HIV-1-envelope glycoprotein (Env) have been isolated from infected persons. The potency of NAbs is measured more often than the size of the persistent fraction of infectivity at maximum neutralizat ...
