The COVID-19 pandemic is bringing about far-reaching structural changes on both the economy and public health, and conventional methodologies have to be fine-tuned to assist public health decision making. In this context, behavioural economics, which is situated at the crossroads between economics and social psychology, is an undeniably innovative field. In contrast with conventional models, the economic models of behavioural economics incorporate psychological and social determinants to produce more accurate predictions of individual behaviour.

Proteomics of Herpes Simplex Virus Type 1 Nuclear Capsids.

J Virol

February 2021

Department of Pathology and Cell Biology, Université de Montréal, Montréal, Québec, Canada H3T 1C5

Herpes simplex virus replicates in the nucleus, where new capsids are assembled. It produces procapsids devoid of nucleic acid but containing the preVP22a scaffold protein. These thermo-unstable particles then mature into A-, B- or C-nuclear icosahedral capsids, depending on their ability to shed the proteolytically processed scaffold and incorporation of the viral genome.

The glycoprotein M of herpes simplex virus 1 (HSV-1) is dynamically relocated from nuclear membranes to the -Golgi network (TGN) during infection, but molecular partners that promote this relocalization are unknown. Furthermore, while the presence of the virus is essential for this phenomenon, it is not clear if this is facilitated by viral or host proteins. Past attempts to characterize glycoprotein M (gM) interacting partners identified the viral protein gN by coimmunoprecipitation and the host protein E-Syt1 through a proteomics approach.

Functional neuroimaging studies using auditory stimuli consistently show activation of the insular cortex. However, due to the limited temporal resolution of non-invasive neuroimaging techniques, the role(s) of the insula in auditory processing remains unclear. As the anterior insula (aI) and the posterior insula (pI) have different connections and are thought to be functionally distinct, it is likely that these two areas contribute differently to auditory processing.

Targeted immunotherapy has improved the outcome of patients with high-risk neuroblastoma (NB). However, immune escape of tumor cells still occurs and about 40% of NB patients relapse and die from their disease. We previously showed that natural killer (NK) cell stimulation by Toll-like receptor (TLR)-activated plasmacytoid dendritic cells (pDC) increases the efficacy of dinutuximab-based immunotherapy against NB cell lines via the TRAIL death-receptor pathway.
