ABSTRACT
Newcastle Disease (ND) vaccines are being used for more than 7 decades, the disease is still a major challenge for poultry industry both locally and internationally. ND frequently emerges in highly vaccinated flocks causing high economic losses without specific treatment. Mesenchymal stem cells (MSCs) are a group of pluripotent cells with multiple biotechnology applications, including but not limited to tissue genesis, tissue repair, hematopoiesis, and immune modulation. Therapeutic strategies based on the usage of stem cells includes the cells either themselves or their secretions (secretome), which has recently shown ability to inhibit SARS-CoV2 replication in-vitro. In this study, MSCs were prepared from the bone marrow of native Egyptian Fayoumi chicken. The MSC with the surface marker CD105 (CD105+) were magnetically separated and infected with virulent Newcastle disease virus (vNDV). The virus-induced multiple changes at the cellular and ultrastructural level in the infected cells, and it was able to maximize the production of interferon-gamma (IFNγ) and interleukin 2 (IL2), interleukin 6 (IL6) and interleukin 12 (IL12). In conclusion, our data represent a preliminary step in vNDV immunotherapy where MSCs media could be used for the treatment of vNDV in infected flocks.
