Transcriptomic Profiling Reveals Altered Expression of Genes Involved in Metabolic and Immune Processes in NDV-Infected Chicken Embryos.

Objective: The poultry industry is significantly impacted by viral infections, particularly Newcastle Disease Virus (NDV), which leads to substantial economic losses. It is essential to comprehend how the sequence of development affects biological pathways and how early exposure to infections might affect immune responses.

Methods: This study employed transcriptome analysis to investigate host-pathogen interactions by analyzing gene expression changes in NDV-infected chicken embryos' lungs.

"Unveiling the genetic symphony: Diversity and expression of chicken genes in Aseel and Kadaknath breeds".

In this investigation, single nucleotide variants (SNVs) within the chicken interferon-inducible transmembrane protein () genes were explored in Aseel and Kadaknath breeds. Comparative analysis with the GRCg6a reference genome revealed 9 and 16 SNVs in the locus for Aseel and Kadaknath breeds, respectively. When referencing the Genome Reference Consortium GRCg7b, Kadaknath exhibited 10 variants, contrasting with none in Aseel.

In Vitro Characterization of of Aseel and Kadaknath Chicken Breeds against Newcastle Disease Virus Infection.

Newcastle disease (ND) is highly contagious and usually causes severe illness that affects all over the world, including domestic poultry. Depending on the virus's virulence, it can impact the nervous, respiratory, and digestive systems and cause up to 100% mortality. The genes are activated in response to viral infection.
