Incorporation of Antibiotics into Solid Lipid Nanoparticles: A Promising Approach to Reduce Antibiotic Resistance Emergence
(MDPI, 2021-05-10)
Antimicrobial resistance is one of the biggest threats to global health as current antibiotics are becoming useless against resistant infectious pathogens. Consequently, new antimicrobial strategies are urgently required. ...
Focal accumulation of aromaticity at the CDRH3 loop mitigates 4E10 polyreactivity without altering its HIV neutralization profile
(Cell Press, 2021-09-24)
Broadly neutralizing antibodies (bnAbs) against HIV-1 are frequently associated with the presence of autoreactivity/polyreactivity, a property that can limit their use as therapeutic agents. The bnAb 4E10, targeting the ...
Co-Existence of blaNDM-1, blaOXA-23, blaOXA-64, blaPER-7 and blaADC-57 in a Clinical Isolate of Acinetobacter baumannii from Alexandria, Egypt
(MDPI, 2023-08-07)
The increasing rates of antimicrobial resistance among carbapenem-resistant Acinetobacter baumannii in the Middle East and North Africa are one of the major concerns for healthcare settings. We characterised the first A. ...
Restoring cellular magnesium balance through Cyclin M4 protects against acetaminophen-induced liver damage
(Nature, 2022-11)
Drug induced liver injury (DILI) is an important cause acute liver failure. Here the authors report that serum Mg2+ serum levels decrease in patients with DILI as well as in preclinical animal models treated with acetaminophen ...
Plasmid content of carbapenem resistant Acinetobacter baumannii isolates belonging to five International Clones collected from hospitals of Alexandria, Egypt
(Frontiers Media, 2023)
Multidrug resistant Acinetobacter baumannii is one of the most important nosocomial pathogens worldwide. During the last decades it has become a major threat for healthcare settings due to the high antibiotic resistance ...
The P. aeruginosa effector Tse5 forms membrane pores disrupting the membrane potential of intoxicated bacteria
(Nature, 2022)
The type VI secretion system (T6SS) of Pseudomonas aeruginosa injects effector proteins into neighbouring competitors and host cells, providing a fitness advantage that allows this opportunistic nosocomial pathogen to ...
Molecular Recognition of the Native HIV-1 MPER Revealed by STED Microscopy of Single Virions
(Springer, 2019-01-08)
Antibodies against the Membrane-Proximal External Region (MPER) of the Env gp41 subunit neutralize HIV-1 with exceptional breadth and potency. Due to the lack of knowledge on the MPER native structure and accessibility, ...
Cholesterol Constrains the Antigenic Configuration of the Membrane-Proximal Neutralizing HIV-1 Epitope
(ACS, 2020-06-25)
The envelope glycoprotein (Env) enables HIV-1 cell entry through fusion of host-cell and viral membranes induced by the transmembrane subunit gp41. Antibodies targeting the C-terminal sequence of the membrane-proximal ...
The commensal bacterium Lactiplantibacillus plantarum imprints innate memory-like responses in mononuclear phagocytes
(Taylor and Francis, 2021-07-05)
Gut microbiota is a constant source of antigens and stimuli to which the resident immune system has developed tolerance. However, the mechanisms by which mononuclear phagocytes, specifically monocytes/macrophages, cope ...
