Phosphatidylserine and phosphatidylethanolamine in mammalian cells: two metabolically related aminophospholipids
Vance JE
Journal of Lipid Research, 49(7), 1377-1387 (2008)
Madhabi Lata Shuma et al.
Biochemistry, 59(18), 1780-1790 (2020-04-15)
The entry of cell-penetrating peptides (CPPs) into live cells and lipid vesicles has been monitored using probe (e.g., fluorescent dye)-labeled CPPs. However, probe labeling may alter the interaction of CPPs with membranes. We have developed a new method to detect

Bioconjugate chemistry, 28(4), 923-932 (2017-03-02)
Artificial systems for controlled membrane fusion applicable for drug delivery would ideally use triggers that are orthogonal to biology. To apply the strain-promoted alkyne-azide cycloaddition (SPAAC) to drive membrane fusion, oxo-dibenzocyclooctyne (ODIBO)-lipid 1 was designed, synthesized, and studied alongside azadibenzocyclooctyne
Assembling responsive microgels at responsive lipid membranes
Wang M, et al.
Proceedings of the National Academy of Sciences of the USA, 116(12), 5442-5450 (2019)
Structural determinants for partitioning of lipids and proteins between coexisting fluid phases in giant plasma membrane vesicles
Sengupta P, et al.
Biochimica et Biophysica Acta - Biomembranes, 1778(1), 20-32 (2008)
Juan Palacios-Ortega et al.
Biochimica et biophysica acta. Biomembranes, 1862(9), 183311-183311 (2020-05-01)
Release of aqueous contents from model lipid vesicles has been a standard procedure to evaluate pore formation efficiency by actinoporins, such as sticholysin II (StnII), for the last few decades. However, regardless of the probe of choice, the results reported

Biophysical journal, 103(11), 2311-2319 (2013-01-04)
A long-standing question about membrane structure and function is the degree to which the physical properties of the inner and outer leaflets of a bilayer are coupled to one another. Using our recently developed methods to prepare asymmetric vesicles, coupling
A Janus -faced IM30 ring involved in thylakoid membrane fusion is assembled from IM30 tetramers
Saur M, et al.
Structure, 25(9) (2017)
Yasunori Watanabe et al.
The Journal of biological chemistry, 295(10), 3257-3268 (2020-02-02)
Eukaryotic cells are compartmentalized to form organelles, whose functions rely on proper phospholipid and protein transport. Here we determined the crystal structure of human VAT-1, a cytosolic soluble protein that was suggested to transfer phosphatidylserine, at 2.2 Å resolution. We

Over the last two decades, supported lipid bilayers (SLBs) have been extensively used as model systems to study cell membrane structure and function. While SLBs have been traditionally produced from simple lipid mixtures, there has been a recent surge in
Fusion of single proteoliposomes with planar, cushioned bilayers in microfluidic flow cells
Karatekin E and Rothman JE
Nature Protocols, 7(5), 903-903 (2012)
Erdem Karatekin et al.
Nature protocols, 7(5), 903-920 (2012-04-21)
Many biological processes rely on membrane fusion, and therefore assays to study its mechanisms are necessary. Here we report an assay with sensitivity to single-vesicle, and even to single-molecule events using fluorescently labeled vesicle-associated v-SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein
Huan Bao et al.
Nature, 554(7691), 260-263 (2018-02-09)
The fusion pore is the first crucial intermediate formed during exocytosis, yet little is known about the mechanisms that determine the size and kinetic properties of these transient structures. Here, we reduced the number of available SNAREs (proteins that mediate
Felista L Tansi et al.
Pharmaceutics, 12(4) (2020-04-23)
Liposomes are biocompatible nanocarriers with promising features for targeted delivery of contrast agents and drugs into the tumor microenvironment, for imaging and therapy purposes. Liposome-based simultaneous targeting of tumor associated fibroblast and the vasculature is promising, but the heterogeneity of

Here, we report on validating a mitochondrial gene therapy by delivering nucleic acids to mitochondria of diseased cells by a MITO-Porter, a liposome-based carrier for mitochondrial delivery. We used cells derived from a patient with a mitochondrial disease with a
