Inhibiting mechanism of Alpiniae oxyphyllae fructus polysaccharide 3 against the replication of porcine epidemic diarrhea virus.

Porcine epidemic diarrhea virus (PEDV) causes diarrhea, vomiting, and death in piglets. Our previous study has revealed the anti-PEDV activity of Alpiniae oxyphyllae fructus polysaccharide 3 (AOFP3). However, it is still unknown whether AOFP3 can inhibit the replication of PEDV.

Inhibition of porcine epidemic diarrhea virus by Alpiniae oxyphyllae fructus polysaccharide 3.

Porcine epidemic diarrhea virus (PEDV) is a deadly pathogen that still plagues suckling piglets. However, there is still no anti-PEDV drug available in clinics. To develop potential anti-PEDV drugs, the antiviral activity of Alpiniae oxyphyllae fructus polysaccharide 3 (AOFP3) against PEDV infection in IPEC-J2 cells were assessed in our present study.

Characterizations of glucose-rich polysaccharides from Amomum longiligulare T.L. Wu fruits and their effects on immunogenicities of infectious bursal disease virus VP2 protein.

The aim of this study is to explore the characterization of Amomum longiligulare T.L. Wu fruits polysaccharide (ALP) and their immune enhancement effects.

Structural characterization of Alpiniae oxyphyllae fructus polysaccharide 2 and its activation effects on RAW264.7 macrophages.

Polysaccharides are important components of Alpiniae oxyphyllae fructus that have been shown to exhibit significant immunomodulatory activity in our previous study. However, whether and how A. oxyphyllae fructus polysaccharides (AOFP) affect macrophages has not been determined.

Okra polysaccharide-2 plays a vital role on the activation of RAW264.7 cells by TLR2/4-mediated signal transduction pathways.

Polysaccharide is the main active component of okra (Abelmoschus esculentus L.) and it can effectively stimulate the activation of macrophages. However, the immune regulatory mechanism is still not clear.

Antiviral activity against porcine epidemic diarrhea virus of Pogostemon cablin polysaccharide.

Ethnopharmacological Relevance: The dry overground parts of Pogostemon cablin (Blanco) Benth. is widely used in China as a traditional Chinese medicine for the treatment of diarrhea, vomiting, nausea and fever. Polysaccharide is an important component of Pogostemon cablin (Blanco) Benth.
