Molecular characterization, tissue expression, and antiviral activities of Bama minipig interferon-α subtypes.

Interferons play a major role in innate immunity and disease resistance. Porcine interferon alpha has 17 subtypes, and their gene sequences, tissue expression profiles, and antiviral activities have been primarily studied in domestic pigs but not in minipigs. Bama minipigs are genetically stable disease-resistant and making them as laboratory animal models for bioscience studies.

Enhancing half-life and cytotoxicity of porcine respiratory and reproductive syndrome virus soluble receptors by taming their Fc domains.

Porcine reproductive and respiratory syndrome virus (PRRSV) is an important pathogen. Although tremendous effort has been made for the vaccine development, only modified live vaccines are widely used with arguably limited efficacy. Our previous study showed that the Fc-fused first four Ig-like domains of Sn (Sn4D-Fc) and the SRCR domains 5-9 of CD163 (SRCR59-Fc) can act as PRRSV soluble receptors (VSRs).

Gene Cloning, Tissue Expression Profiles and Antiviral Activities of Interferon-β from Two Chinese Miniature Pig Breeds.

The porcine interferon (PoIFN) complex represents an ideal model for studying IFN evolution which has resulted from viral pressure during domestication. Bama and Banna miniature pigs are the two Chinese miniature pig breeds that have been developed as laboratory animal models for studying virus infection, pathogenesis, and vaccine evaluation. However, the PoIFN complex of such miniature pig breeds remains to be studied.

Epidemiology of CoViD-19 Pandemic: Recovery and mortality ratio around the globe.

Coronavirus Disease 2019 (CoViD-19) is the third type of coronavirus disease after severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) that appears in human population from the past two decades. It is highly contagious and rapidly spread in the human population and compelled global public health institutions on high alert. Due to genetic similarity of this novel coronavirus 2019 with bat virus its emergence from bat to humans is possible.
