Immunostimulatory effect of beta-glucan at drug-induced immunosuppression in guinea pigs

Біологія тварин, 2020
The peculiarity of beta-glucan action is the effect on all leukocyte populations, which is accompanied by the activation of phagocytic function. Corticosteroid hormones have an immunosuppressive effect.

Characterization of peroxidase and catalase genes in defense mechanisms of Physcomitrella patens [PDF]

, 2019
Systemic acquired resistance (SAR) and the hypersensitive response (HR) are two important induced defense mechanisms in plants. SAR is the development of an enhanced resistance to a pathogen due to a prior encounter.

Some putative prebiotics increase the severity of serovar Typhimurium infection in mice [PDF]

, 2009
Prebiotics are non-digestible food ingredients believed to beneficially affect host health by selectively stimulating the growth of the beneficial bacteria residing in the gut.

Thermal Expansion Coefficient of Curdlan Tripropionate Measured by Thermal Mechanical Analysis and Wide‐Angle X‐Ray Diffraction

Journal of Applied Polymer Science, EarlyView.
This study demonstrates the thermal expansion behavior of curdlan tripropionate films using thermal mechanical analysis and synchrotron WAXD. Both amorphous and crystalline films show characteristic expansion near the glass transition, providing structural insights for designing heat‐resistant polysaccharide‐based plastics.

Cyclic β-glucans at the bacteria–host cells interphase: One sugar ring to rule them all [PDF]

, 2018
Cyclic β‐1,2‐D‐glucans (CβG) are natural bionanopolymers present in the periplasmic space of many Proteobacteria. These molecules are sugar rings made of 17 to 25 D‐glucose units linked exclusively by β‐1,2‐glycosidic bonds.

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

BMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

Oral beta-glucan adjuvant therapy converts nonprotective Th2 response to protective Th1 cell-mediated immune response in mammary tumor-bearing mice.

Folia Histochemica et Cytobiologica, 2007
Beta (1-3)-D-glucans were identified almost 40 years ago as biological response modifiers that stimulated tumor rejection. In vitro studies have shown that beta-glucans bind to a lectin domain within complement receptor type 3 (CR3), or to, more recently

Influence of Feeding Enzymatically Hydrolyzed Yeast Cell Wall on Growth Performance and Digestive Function of Feedlot Cattle during Periods of Elevated Ambient Temperature. [PDF]

, 2015
In experiment 1, eighty crossbred steers (239±15 kg) were used in a 229-d experiment to evaluate the effects of increasing levels of enzymatically hydrolyzed yeast (EHY) cell wall in diets on growth performance feedlot cattle during periods of elevated ...
