Erythrocyte Membrane Lipids and Rh Antigen Activity

open access: yesJournal of Biological Chemistry, 1972
The Rh antigens have never been totally and reproducibly obtained in free solution. Indirect evidence, based among other observations on the reversible loss of Rh antigen activity of lyophilized Rh-positive erythrocyte membranes with mercurial sulfhydryl reagents, suggests that the activity may depend on membrane protein.

Biomimetic Copper Nanoparticles Coated with ACE2‐Overexpressing Membranes for Selective SARS‐CoV‐2 Neutralization and Disinfection

open access: yesAdvanced Healthcare Materials, EarlyView.
By fusing ACE2‐overexpressing membrane‐integrated liposome (MIL) with copper nanoparticles, the biomimetic Cu@MIL nanostructures were created that directly hijack the SARS‐CoV‐2 entry pathway. These particles combine potent virus‐targeting precision with intrinsic antiviral activity, achieving rapid neutralization and disinfection.

Effect of lipid peroxidation on the immunocytochemical detection of a leukocyte antigenic determinant in fresh and cryopreserved bovine spermatozoa

open access: yesItalian Journal of Animal Science, 2010
Studies on different species, including rats, monkeys and humans, have shown the presence of leukocyte differentiationantigens in the spermatozoa. In some case the expression of these molecules is related to a specific functional state ofthe sperm cell ...

Spirochetal Lipoproteins and Immune Evasion. [PDF]

open access: yes, 2017
Spirochetes are a major threat to public health. However, the exact pathogenesis of spirochetal diseases remains unclear. Spirochetes express lipoproteins that often determine the cross talk between the host and spirochetes.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

open access: yesAdvanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Extracellular Vesicles Modulation by an Adiponectin Receptor Agonist Provides Cardioprotection for Myocardial Ischemic Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
This study demonstrates that ALY688, a drug mimicking the heart‐protective hormone adiponectin, reduces myocardial ischemia injury. ALY688 increases the production of extracellular vesicles, which carry protective cargo including adiponectin itself.

Partial chemical characterization of antigenic preparations of chromoblastomycosis agents Caracterização química parcial de preparações antigênicas de agentes da cromoblastomicose

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 1999
Antigenic preparations (saline, methylic, metabolic and exoantigens) of four agents of chromoblastomycosis, Fonsecaea pedrosoi, Phialophora verrucosa, Cladophialophora (Cladosporium) carrionii and Rhinocladiella aquaspersa were obtained. Partial chemical

Peroxisome proliferator-activated receptor (PPAR)alpha expression in T cells mediates gender differences in development of T cell-mediated autoimmunity. [PDF]

open access: yes, 2007
Peroxisome proliferator-activated receptor (PPAR)alpha is a nuclear receptor that mediates gender differences in lipid metabolism. PPARalpha also functions to control inflammatory responses by repressing the activity of nuclear factor kappaB (NF-kappaB ...
