Membrane permeabilization by trypanosome lytic factor, a cytolytic human high density lipoprotein
Harrington JM, et al.
The Journal of Biological Chemistry, 284(20), 13505-13512 (2009)
Xianping Li et al.
Infection and immunity, 80(1), 429-440 (2011-11-16)
Aspergillus fumigatus is the most prevalent airborne fungal pathogen that induces serious infections in immunocompromised patients. Phospholipases are key enzymes in pathogenic fungi that cleave host phospholipids, resulting in membrane destabilization and host cell penetration. However, knowledge of the impact...

mBio, 11(2) (2020-04-16)
To overcome increasing bacterial resistance to conventional antibiotics, many antimicrobial peptides (AMPs) derived from host defense proteins have been developed. However, there are considerable obstacles to their application to systemic infections because of their low bioavailability. In the present study...

Molecular psychiatry (2020-05-07)
Delivery of drugs into the brain is poor due to the blood brain barrier (BBB). This study describes the development of a novel liposome-based brain-targeting drug delivery system. The liposomes incorporate a diacylglycerol moiety coupled through a linker to a...
John M Harrington et al.
The Journal of biological chemistry, 284(20), 13505-13512 (2009-03-28)
Trypanosome lytic factor (TLF) is a subclass of human high density lipoprotein (HDL) that mediates an innate immune killing of certain mammalian trypanosomes, most notably Trypanosoma brucei brucei, the causative agent of a wasting disease in cattle. Mechanistically, killing is...

PloS one, 12(4), e0174706-e0174706 (2017-04-07)
RAS mutations lead to a constitutively active oncogenic protein that signals through multiple effector pathways. In this chemical biology study, we describe a novel coupled biochemical assay that measures activation of the effector BRAF by prenylated KRASG12V in a lipid-dependent...
Gabriel García-Molina et al.
Bioelectrochemistry (Amsterdam, Netherlands), 133, 107490-107490 (2020-03-04)
Adenosine triphosphate (ATP) is a key molecule as energy vector for living organisms, therefore its detection reveals the presence of microbial colonies. Environments where the existence of microbial pathogens suppose a health hazard can benefit from real time monitoring of...
Anne Araye et al.
PloS one, 11(4), e0153401-e0153401 (2016-04-14)
Botulinum neurotoxin A (BoNT/A) is composed of three domains: a catalytic domain (LC), a translocation domain (HN) and a receptor-binding domain (HC). Like most bacterial toxins BoNT/A is an amphitropic protein, produced in a soluble form that is able to...
Hepatitis B virus X protein induces size-selective membrane permeabilization through interaction with cardiolipin
You DG, et al.
Biochimica et Biophysica Acta - Biomembranes, 1861(4), 729-737 (2019)
Dieter R Klopfenstein et al.
Molecular biology of the cell, 15(8), 3729-3739 (2004-05-25)
UNC-104 (KIF1A) is a kinesin motor that transports synaptic vesicles from the neuronal cell body to the terminal. Previous in vitro studies have shown that a Dictyostelium relative of UNC-104 transports liposomes containing acidic phospholipids, but whether this interaction is...
Effects of lipid composition on the structural properties of human serum amyloid A in reconstituted high-density lipoprotein particles
Takase H, et al.
Chemistry and Physics of Lipids, 221, 8-14 (2019)
Giada Dogliotti et al.
Nature communications, 8, 15747-15747 (2017-06-27)
The serine/threonine kinase LKB1 regulates various cellular processes such as cell proliferation, energy homeostasis and cell polarity and is frequently downregulated in various tumours. Many downstream pathways controlled by LKB1 have been described but little is known about the upstream...
Kai Cai et al.
The Biochemical journal, 454(2), 267-274 (2013-06-19)
DGKs (diacylglycerol kinases) catalyse the conversion of diacylglycerol into PA (phosphatidic acid), a positive modulator of mTOR (mammalian target of rapamycin). We have found that chenodeoxycholic acid and the synthetic FXR (farnesoid X receptor) ligand GW4064 induce the mRNA and...
Biochemistry of Lipids, Lipoproteins and Membranes (1996)
Muscle and Exercise Physiology (2018)
Dieter R Klopfenstein et al.
Cell, 109(3), 347-358 (2002-05-23)
Unc104 (KIF1A) kinesin transports membrane vesicles along microtubules in lower and higher eukaryotes. Using an in vitro motility assay, we show that Unc104 uses a lipid binding pleckstrin homology (PH) domain to dock onto membrane cargo. Through its PH domain...

PLoS genetics, 6(11), e1001200-e1001200 (2010-11-17)
UNC-104/KIF1A is a Kinesin-3 motor that transports synaptic vesicles from the cell body towards the synapse by binding to PI(4,5)P(2) through its PH domain. The fate of the motor upon reaching the synapse is not known. We found that wild-type...
