Cell-envelope remodeling as a determinant of phenotypic antibacterial tolerance in mycobacterium tuberculosis
(2016-05-13)
The mechanisms that lead to phenotypic antibacterial tolerance in bacteria remain poorly understood. We investigate whether changes in NaCl concentration toward physiologically higher values affect antibacterial efficacy ...
Changes in the lipid composition of Bradyrhizobium cell envelope reveal a rapid response to water deficit involving lysophosphatidylethanolamine synthesis from phosphatidylethanolamine in outer membrane
(Elsevier Science, 2018-07)
We evaluate the behavior of the membrane of Bradyrhizobium sp. SEMIA6144 during adaptation to polyethylene glycol (PEG). A dehydrating effect on the morphology of the cell surface, as well as a fluidizing effect on the ...
Structural associations between organelle membranes in nectary parenchyma cells
(2018-05-01)
Main conclusion: The close association between membranes and organelles, and the intense chloroplast remodeling in parenchyma cells of extrafloral nectaries occurred only at the secretion time and suggest a relationship ...
E-cadherin expression pattern during zebrafish embryonic epidermis development [version 3; referees: 3 approved]
(F1000 Research Ltd, 2018-12)
Background: E-cadherin is the major adhesion receptor in epithelial adherens junctions (AJs). On established epidermis, E-cadherin performs fine-tuned cell-cell contact remodeling to maintain tissue integrity, which is ...
Daptomycin-resistant enterococcus faecalis diverts the antibiotic molecule from the division septum and remodels cell membrane phospholipids
(American Society for Microbiology, 2013)
Treatment of multidrug-resistant enterococci has become a challenging clinical problem in hospitals around the world due to the lack of reliable therapeutic options. Daptomycin (DAP), a cell membrane-targeting cationic ...

Avaliação da inibição da atividade da fosfolipase citoplasmática A2 (cPLA2) sobre o ciclo de multiplicação do Vaccinia virus
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE MICROBIOLOGIAPrograma de Pós-Graduação em MicrobiologiaUFMG, 2017-03-31)
Vaccinia virus (VACV), the prototype virus of the Poxviridae family, is an enveloped virus that carries out its multiplicative cycle entirely in the cytoplasm of the host cell. Throughout its multiplication cycle, VACV ...
The PmrAB system-inducing conditions control both lipid A remodeling and O-antigen length distribution, influencing the Salmonella typhimurium-host interactions
(American Society for Biochemistry and Molecular Biology, 2012-11)
The Salmonella enterica serovar Typhimurium lipopolysaccharide consisting of covalently linked lipid A, non-repeating core oligosaccharide, and the O-antigen polysaccharide is the most exposed component of the cell envelope. ...

The Salmonella enterica serovar Typhimurium lipopolysaccharide consisting of covalently linked lipid A, non-repeating core oligosaccharide and the O-antigen polysaccharide, is the most exposed component of the cell envelope. ...
Cellular Organelles Reorganization During Zika Virus Infection of Human Cells
(Frontiers Media, 2020-07)
Zika virus (ZIKV) is an enveloped positive stranded RNA virus belonging to the genus Flavivirus in the family Flaviviridae that emerged in recent decades causing pandemic outbreaks of human infections occasionally associated ...
