Preliminary study of the toxicity and radioprotective effects of zymosan in vitro and in vivo
Background This study aimed to confirm the cytotoxicity of zymosan in vitro and in vivo and determine the appropriate treatment time and the dose of zymosan. Methods AHH-1 cells and HIECs were administered by 0, 20, 40, 80 or 160 μg/mL zymosan. The CCK-8

Block of death-receptor apoptosis protects mouse cytomegalovirus from macrophages and is a determinant of virulence in immunodeficient hosts. [PDF]
The inhibition of death-receptor apoptosis is a conserved viral function. The murine cytomegalovirus (MCMV) gene M36 is a sequence and functional homologue of the human cytomegalovirus gene UL36, and it encodes an inhibitor of apoptosis that binds to ...

Supersulfide biology and translational medicine for disease control
Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen

The role of the host—Neutrophil biology
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Anti-cancer T-cell responses are often halted due to the immune-suppressive micro-environment, in part related to tumor-associated macrophages. In the current study, we assessed indigestible β-glucans (oatβG, curdlan, grifolan, schizophyllan, lentinan ...

Zymosan-A promotes the regeneration of intestinal stem cells by upregulating ASCL2
Intestinal stem cells (ISCs) are responsible for intestinal tissue homeostasis and are important for the regeneration of the damaged intestinal epithelia. Through the establishment of ionizing radiation (IR) induced intestinal injury model, we found that

Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene cause autosomal dominant Parkinson’s disease (PD), with the most common causative mutation being the LRRK2 p.G2019S within the kinase domain.

Downregulation of neutrophil CD43 by opsonized zymosan [PDF]
Abstract CD43, a prevalent white blood cell molecule distinguished by its mucin- like surface region, has been proposed as a “functional barrier” that prevents or negatively regulates a variety of cell surface interactions. Implicit in this hypothesis is the expectation that CD43 will be altered or removed when white blood cells are ...

Phagocytosis of zymosan by human neutrophils [PDF]
A rapid cellular response occurs when human neutrophils are challenged with the zymosan particle. Monolayers of neutrophils adhering to glass were incubated with opsonized zymosan at 37°C for 15 sec to 3 min, fixed and prepared for observation by SEM, immunofluorescence or TEM.
