Molecular characterization and immunostimulant-induced expression analysis of type I interferon gene in Labeo bata (Ham.)
Immunostimulants stimulate the immune system by involving many cytokines. Interferons, a crucial cytokine, shares both antiviral and antibacterial properties. Hence, the present study aimed to evaluate the effect of immunostimulant on type I interferon (I-IFNs) gene expression in Labeo bata. For the...

Immunostimulants stimulate the immune system by involving many cytokines. Interferons, a crucial cytokine, shares both antiviral and antibacterial properties.

For the first time, genes coding for I-IFN has been cloned, amplified, and sequenced from L. bata (bata). The sequence analysis revealed that bata I-IFN consists of 1,800 bp genomic sequence with five exons and four introns and an ORF of 537 bp encoding for a putative protein of 178 amino acids.
