Human PSGL-1 is a receptor for EV71 that facilitates EV71 entry and replication in mouse cells. We have evaluated the role of human PSGL-1 in EV71 infection in vivo using a transgenic mouse line. Expression of human PSGL-1 failed to enhance infectivity of clinical EV71 strains in mice; however, it promoted replication and symptom severity at an earlier stage in mice upon infection with a mouse-adapted EV71 strain. We therefore conclude that human PSGL-1 alone is not sufficient to modulate infection with the clinical EV71 strains of genotype C4 in mice.

B cells have emerged as central players in the tumor microenvironment (TME) of non-small cell lung cancer (NSCLC). However, although there is clear evidence for their involvement in cancer immunity, scanty data exist on the characterization of B cell phenotypes, bioenergetic profiles and possible interactions with T cells in the context of NSCLC. In this study, using polychromatic flow cytometry, mass cytometry, and spatial transcriptomics we explored the intricate landscape of B cell phenotypes, bioenergetics, and their interaction with T cells in NSCLC.

Fucosylated chondroitin sulfate (FCS) from Holothuria mexicana (FCS) was selected for investigation because of its intriguing branch features. Selective β-eliminative depolymerization and the bottom-up assembly were performed to unravel that FCS consisted of a {D-GlcA-β1,3-D-GalNAc} backbone and branches of alternating Fuc (55 %) and D-GalNAc-α1,2-L-Fuc (45 %), the highest proportion of disaccharide branch reported to date. In branches, sulfation could occur at every free -OH site except O-3 of GalNAc, being the most complex and various structure features of natural FCS.

This study defines biochemical mechanisms that contribute to novel neural-regenerative activities we recently demonstrated for thiol-modified ManNAc analogs in human neural stem cells (hNSCs) by comparing our lead drug candidate for brain repair, "TProp," to a "size-matched" N-alkyl control analog, "But." These analogs biosynthetically install non-natural sialic acids into cell surface glycans, altering cell surface receptor activity and adhesive properties of cells. In this study, TProp modulated sialic acid-related biology in hNSCs to promote neuronal differentiation through modulation of cell adhesion molecules (integrins α6, β1, E-cadherin, and PSGL-1) and stem cell markers.

The surface of HIV-1 is embedded with numerous host-derived proteins. Characterizing these proteins can enhance knowledge of virus biology and potentially identify novel therapeutic targets. As many of these proteins are present in low abundance on virion surfaces, their identification can be hindered by inherent variables in the methods employed to detect them, including their varying assay sensitivities, sample processing, quantitative capacity, and experimental reproducibility.

Background: Human glioblastoma multiforme (GBM) is a highly aggressive tumor with insufficient therapies available. Especially, novel concepts of immune therapies fail due to a complex immunosuppressive microenvironment, high mutational rates, and inter-patient variations. The intratumoral heterogeneity is currently not sufficiently investigated.
