recommendations! Published in 2021 at "Cell reports"

DOI: 10.1016/j.celrep.2021.109923

Abstract: The dense variant surface glycoprotein (VSG) coat of African trypanosomes represents the primary host-pathogen interface. Antigenic variation prevents clearing of the pathogen by employing a large repertoire of antigenically distinct VSG genes, thus neutralizing the… read more here.

DOI: 10.1016/j.epsr.2021.107289

Abstract: Abstract In this paper, a self-regulated virtual impedance (SRVI) control of virtual synchronous generator (VSG) is proposed. In the modern power system, large penetration of inverter-interfaced distributed generator (DG) decreases the equivalent inertia of the… read more here.

DOI: 10.1016/j.molbiopara.2018.10.003

Abstract: Trypanosoma brucei relies on two types of variant surface glycoprotein (VSG) expression sites (ESs) for RNA polymerase I (Pol I) transcription of VSG pre-mRNA. Trypanosomes developing into infectious metacyclic cells in the tsetse vector use… read more here.

DOI: 10.1016/j.molmet.2022.101432

Abstract: Objective Vertical Sleeve Gastrectomy (VSG) is one of the most efficacious treatments for obesity and its comorbidities. Although a range of evidence suggests that alterations of the microbiota in the distal gut following VSG are… read more here.

DOI: 10.1017/s003118201700004x

Abstract: SUMMARY Trypanosoma equiperdum possesses a dense coat of a variant surface glycoprotein (VSG) that is used to evade the host immune response by a process known as antigenic variation. Soluble and membrane forms of the… read more here.

DOI: 10.1038/s41467-020-14575-8

Abstract: African trypanosomes (Trypanosoma) are vector-borne haemoparasites that survive in the vertebrate bloodstream through antigenic variation of their Variant Surface Glycoprotein (VSG). Recombination, or rather segmented gene conversion, is fundamental in Trypanosoma brucei for both VSG… read more here.

DOI: 10.1038/s41564-017-0013-6

Abstract: The most prominent defence of the unicellular parasite Trypanosoma brucei against the host immune system is a dense coat that comprises a variant surface glycoprotein (VSG). Despite the importance of the VSG family, no complete… read more here.

DOI: 10.1038/s41586-024-08151-z

Abstract: The protozoan parasite Trypanosoma brucei evades clearance by the host immune system through antigenic variation of its dense variant surface glycoprotein (VSG) coat, periodically ‘switching’ expression of the VSG using a large genomic repertoire of… read more here.

DOI: 10.1038/s41598-021-81866-5

Abstract: Vertical sleeve gastrectomy (VSG) is the most commonly performed bariatric/metabolic surgery, exhibiting a high rate of diabetes remission in humans. To elucidate the molecular mechanisms of VSG, we performed transcriptomic analysis of the liver, fat,… read more here.

DOI: 10.1049/rpg2.13118

Abstract: The high penetration of renewable energy sources (RES) results in a low‐inertia, weak power grid. To mitigate this and restore system inertia, it has been widely proposed to operate the inverters of RES units to… read more here.
