NFKB1 and infectious disease: Aspects such as the expression and regulation of FGF genes in pathogen infection and the regulation of FGF genes in the development of chicken embryos, cytokine expression, apoptosis, or immune system through regulation of signaling pathways, immune pathway, apoptosis pathway, or development pathway in chickens, such as in the response to infectious diseases, NF-κB signaling pathway, JAK-STAT signaling pathway, toll like receptor pathway, apoptosis pathway, cell cycle, or B-T cell signaling pathway should be addressed.
