Antibacterial, anti-inflammatory and antioxidant activities of Mahanintangtong and its constituent herbs, a formula used in Thai traditional medicine for treating pharyngitis.

Background: Mahanintangtong is listed in the Thailand's National List of Essential Medicines (NLEM). It is used to treat non-specific fevers and illnesses such as pharyngitis and chickenpox. In this study, we investigated the biological activities of the different medicinal plants used in the Mahanintangtong formula.

Ligand-competent fractalkine receptor is expressed on exosomes.

Expression of chemokine receptor CX3CR1 is reportedly restricted to several cell types including natural killer cells, cytotoxic T cells, monocytes, and macrophages. However, its expression and function on exosomes, which are nanosized extracellular vesicles known to act as mediators of intercellular communications, remain unclear. Here, we investigated CX3CR1 expression on exosomes isolated from various cell types.

Anti-, Anti-Inflammatory, Cytotoxic, and Antioxidant Activities of Mace Extracts from .

The aril (mace) of , known as Dok-Chan, is a spice that has long been used for treating stomach discomfort, peptic ulcer, and nausea. It is an ingredient in many remedies in Thai traditional medicine, e.g.

Talin-2 regulates integrin functions in exosomes.

Integrins on exosomes have been shown to mediate binding to recipient cells, potentially playing important roles in controlling exosomal internalization and organ distributions. Although the ability of cellular integrins to mediate cell adhesion is known to be regulated by the cytoplasmic adaptor protein talin, whether the activity of exosomal integrins is similarly regulated by talin remains to be elucidated. Here we have studied this question in T-cell exosomes that surface express the integrins αLβ2 and α4β7.

Anti-adhesive effects of human soluble thrombomodulin and its domains.

We reported previously that leukocyte β2 integrins (LFA-1 and Mac-1) bind to the serine/threonine-rich domain of thrombomodulin (TM) expressed on vascular endothelial cells (VECs). Recombinant human soluble TM (rhsTM, TMD123) has been approved as a therapeutic drug for septic disseminated intravascular coagulation. However, the roles of TMD123 on the adhesion of leukocyte integrins to VECs remain unclear.

Exosomal regulation of lymphocyte homing to the gut.

Exosomes secreted from T cells have been shown to affect dendritic cells, cancer cells, and other T cells. However, little is known about how T-cell exosomes (T exosomes) modulate endothelial cell functions in the context of tissue-specific homing. Here, we study the roles of T exosomes in the regulation of gut-specific T-cell homing.

Integrin and PD-1 Ligand Expression on Circulating Extracellular Vesicles in Systemic Inflammatory Response Syndrome and Sepsis.

Extracellular vesicles (EVs) in the plasma mediate important intercellular communications in the pathogenesis of cancer and inflammatory diseases. EVs express integrins that regulate target specificities and programmed cell death ligand 1 and 2 (PD-L1 and 2) that suppress lymphocyte activation. However, the roles of these molecules on EVs in systemic inflammatory response syndrome (SIRS) and sepsis remain little understood.

Cytotoxic, Anti-inflammatory and Antioxidant Activities of Heliotropium indicum Extracts.

Background: Heliotropium indicum Linn., or ‘Indian heliotrope’ is very common in India with a long history of traditional medicinal uses in many countries in the world. In Thailand, the plant has been traditionally use to cure various diseases such as fever, insect bites, stings, diarrhea, skin rashes, menstrual disorder and urticaria.

Antimicrobial activity of Thai medicinal preparation of Khampramong Temple used for cancer treatment and its plant components.

Background: Thai medicinal preparation of Khampramong Temple has been used for cancer treatment more than ten years ago. It is composed of eleven herbs. Many anticancer drugs exhibited antimicrobial activity as antitumor antibiotics such as the anthracycline group [daunorubicin] and quinone group [mitomycin C].
