Identification of a small RNA containing the trypanosome spliced leader: a donor of shared 5' sequences of trypanosomatid mRNAs? [PDF]
, 1984 The 35 nucleotide spliced leader (SL) sequence is found on the 5' end of numerous trypanosome mRNAs, yet the tandemly organized reiteration units encoding this leader are not detectably linked to any of these structural genes. Here we report the presence

Advanced Healthcare Materials, EarlyView.Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

The Prefusogenic Intermediate of HIV-1 gp41 Contains Exposed C-peptide Regions [PDF]
, 2003 The human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein is composed of a complex between the surface subunit gp120, which binds to cellular receptors, and the transmembrane subunit gp41.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction
Advanced Healthcare Materials, EarlyView.Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Mosaic VSGs and the scale of Trypanosoma brucei antigenic variation.
PLoS Pathogens, 2013 A main determinant of prolonged Trypanosoma brucei infection and transmission and success of the parasite is the interplay between host acquired immunity and antigenic variation of the parasite variant surface glycoprotein (VSG) coat.

Variant surface glycoprotein gene expression site switches in Trypanosoma brucei.
Journal of Biological Chemistry, 1986 In Trypanosoma brucei bloodstream forms, transcription of variant surface glycoprotein (VSG) genes occurs at only one of several possible expression sites at any given time. Activation and inactivation of some expression sites are correlated with recombinational events that alter their chromosomal position (Van der Ploeg, L. H. T., Cornelissen, A. W. C.
