Aging Intensifies Myeloperoxidase Activity after Ischemic Stroke.

Abnormally elevated oxidative stress underlies many diseases and contributes to aging. The myeloid enzyme myeloperoxidase (MPO) generates oxidative stress and contributes to damage after stroke. How aging changes MPO in stroke has not been studied.

Basic Science of Neuroinflammation and Involvement of the Inflammatory Response in Disorders of the Nervous System.

Neuroinflammation is a key immune response observed in many neurologic diseases. Although an appropriate immune response can be beneficial, aberrant activation of this response recruits excessive proinflammatory cells to cause damage. Because the central nervous system is separated from the periphery by the blood-brain barrier (BBB) that creates an immune-privileged site, it has its own unique immune cells and immune response.

Aminooxy acetic acid suppresses Th17-mediated psoriasis-like skin inflammation by inhibiting serine metabolism.

Psoriasis is a common chronic inflammatory skin disease characterized by an external red rash that is caused by abnormal proliferation and differentiation of keratinocytes and immune T cells. This study aimed to elucidate the role of aminooxy acetic acid (AOA) in alleviating psoriasis from the perspective of immunology and metabolomics. Therefore, contributing to the development of new drugs as candidates for psoriasis treatment.

Wheatgrass-and-Aronia-Mixed Extract Suppresses Immunoglobulin E-Mediated Allergic Reactions In Vitro and In Vivo.

Mast cells are an important component of immune responses. Immunoglobulin (Ig) E-sensitized mast cells release substances within minutes of allergen exposure, triggering allergic responses. Until now, numerous pharmacological effects of wheatgrass and aronia have been verified, but the effects of wheatgrass and aronia (TAAR)-mixed extract on allergic reactions have not been identified.

Extract of Wheatgrass and Aronia Mixture Ameliorates Atopic Dermatitis-Related Symptoms by Suppressing Inflammatory Response and Oxidative Stress In Vitro and In Vivo.

Atopic dermatitis is regulated by the production of pro-inflammatory cytokines and chemokines via the nuclear factor kappa B or mitogen-activated protein kinase signaling pathways, as well as, the release of oxidative stress-related factors via the NF-E2 p45-related factor 2 signaling pathway. Both wheatgrass ( L., TA) and aronia (, AR) are known for their anti-inflammatory and antioxidant properties, however, the anti-inflammatory and antioxidant effects of TA and AR (TAAR) mixture extract have not been elucidated in an atopic dermatitis model.

Mast cell modulates tumorigenesis caused by repeated bowel inflammation condition in azoxymethane/dextran sodium sulfate-induced colon cancer mouse model.

Mast cells infiltrate the inflammatory microenvironment and regulate the production of many pro-inflammatory cytokines and mediators of inflammatory cell production to promote tumor development and growth in intestinal lesions. Currently, there are insufficient studies of the mediators and signaling pathways regulated by mast cells that influence the pathogenesis of colon cancer in inflamed colon tissue. This study aimed to confirm the role of mast cells in the incidence and growth of colitis-associated colon cancer (CAC) and to identify inflammation-mediated factors and signaling pathways related to tumor development.

Blume and Siebold & Zucc Mixed Extract Suppress Platelet Aggregation and Thrombosis.

Blood vessel thrombosis causes blood circulation disorders, leading to various diseases. Currently, various antiplatelet and anticoagulant drugs, such as aspirin, warfarin, heparin, and non-vitamin K antagonist oral anticoagulants (NOACs), are used as the major drugs for the treatment of a wide range of thrombosis. However, these drugs have a side effect of possibly causing internal bleeding due to poor hemostasis when taken for a long period of time.

Inhibitory Effect of Fractions on Melanogenesis in α-MSH-Stimulated B16-F10 Melanoma Cells.
