Use of the chemical permeabilization process in yeast cells: production of high-activity whole cell biocatalysts [PDF]

BioTechnologia, 2020
Yeast cells are popular microorganisms for use in various bioprocesses because of their ability to produce various enzymes. They are also known for their low price. However, the activity of these biocatalysts is limited by cell membrane diffusion. One of

Carbon monoxide prevents hepatic mitochondrial membrane permeabilization [PDF]

BMC Cell Biology, 2011
Background Low concentrations of carbon monoxide (CO) protect hepatocytes against apoptosis and confers cytoprotection in several models of liver. Mitochondria are key organelles in cell death control via their membrane permeabilization and the release ...

Does the shape of the electric pulse matter in electroporation?

Frontiers in Oncology, 2022
Electric pulses are widely used in biology, medicine, industry, and food processing. Numerous studies indicate that electroporation (EP) is a pulse-dependent process, and the electric pulse shape and duration strongly determine permeabilization efficacy.

Transcriptional Profiling of CD8+ CMV-Specific T Cell Functional Subsets Obtained Using a Modified Method for Isolating High-Quality RNA From Fixed and Permeabilized Cells

Frontiers in Immunology, 2020
Previous studies suggest that the presence of antigen-specific polyfunctional T cells is correlated with improved pathogen clearance, disease control, and clinical outcomes; however, the molecular mechanisms responsible for the generation, function, and ...

Membrane permeabilization by α-helical peptides: a flow cytometry study [PDF]

, 1995
The permeabilization by α-helical peptides of nucleated mammalian cells can be monitored by flow cytometry. Ethidium bromide, a non fluorescent and poorly membrane permeant molecule, becomes strongly fluorescent only upon binding to DNA.

Lysophosphatidylcholine-induced cellular injury in cultured fibroblasts involves oxidative events

Journal of Lipid Research, 2000
Lysophosphatidylcholine (lysoPC), formed during LDL oxidation and located within atherosclerotic plaques, induces numerous cellular responses, but via unknown mechanisms.

A cardinal role for cathepsin D in co-ordinating the host-mediated apoptosis of macrophages and killing of pneumococci [PDF]

, 2011
The bactericidal function of macrophages against pneumococci is enhanced by their apoptotic demise, which is controlled by the anti-apoptotic protein Mcl-1.
