Indoleamine 2, 3-dioxygenase 1 mediated alterations in the functionality of immune cells, deciphers the pregnancy outcomes in crossbred dairy cows.

Pregnancy establishment in bovines requires maternal immune cell modulation. Present study investigated possible role of immunosuppressive indolamine-2, 3-dioxygenase 1 (IDO1) enzyme in the alteration of neutrophil (NEUT) and peripheral blood mononuclear cells (PBMCs) functionality of crossbred cows. Blood was collected from non-pregnant (NP) and pregnant (P) cows, followed by isolation of NEUT and PBMCs.

Proteomics and transcriptomics study reveals the utility of ISGs as novel molecules for early pregnancy diagnosis in dairy cows.

An early and precise diagnosis of pregnancy in cows is critical to short the calving interval and to improve their reproductive efficiency. Neutrophils are the first blood cells to sensitize the embryo in the uterus and participate in maternal recognition of pregnancy after getting induced by interferon tau (IFNτ). To study the protein abundance ratio, blood samples were collected on 0th, 10th, 18th and 36th day post-artificial insemination (AI) from crossbred Karan Fries cows.

Expression and characterization of the non-structural protein V of small ruminant morbillivirus.

Peste-des-petits ruminants is a transboundary viral disease of small ruminants caused by small ruminant morbillivirus (SRMV). In the present study, the full-length V gene of SRMV was constructed through site-directed mutagenesis from the P gene transcripts of the vaccine virus (Sungri/96 India) and expressed in a prokaryotic expression system. In animals, the seroconversion against this protein occurs from 14-days and is getting produced from 48 h in cell culture.

Contrasting Gene Expression Profiles of Monocytes and Lymphocytes From Peste-Des-Petits-Ruminants Virus Infected Goats.

In this study, transcriptome analysis of PPRV infected PBMC subsets-T helper cells, T cytotoxic cells, monocytes, and B lymphocytes was done to delineate their role in host response. PPRV was found to infect lymphocytes and not monocytes. The established receptor for PPRV-SLAM was found downregulated in lymphocytes and non-differentially expressed in monocytes.

Selection and validation of suitable reference genes for qPCR gene expression analysis in goats and sheep under Peste des petits ruminants virus (PPRV), lineage IV infection.

Identification of suitable candidate reference genes is an important prerequisite for validating the gene expression data obtained from downstream analysis of RNA sequencing using quantitative real time PCR (qRT-PCR). Though existence of a universal reference gene is myth, commonly used reference genes can be assessed for expression stability to confer their suitability to be used as candidate reference genes in gene expression studies. In this study, we evaluated the expression stability of ten most commonly used reference genes (GAPDH, ACTB, HSP90, HMBS, 18S rRNA, B2M, POLR2A, HPRT1, ACAC, YWHAZ) in fourteen different Peste des petits ruminants virus (PPRV) infected tissues of goats and sheep.

Sequence-based comparative study of classical swine fever virus genogroup 2.2 isolate with pestivirus reference strains.

Aim: This study was undertaken with the aim to compare and establish the genetic relatedness between classical swine fever virus (CSFV) genogroup 2.2 isolate and pestivirus reference strains.

Materials And Methods: The available complete genome sequences of CSFV/IND/UK/LAL-290 strain and other pestivirus reference strains were retrieved from GenBank.

Whole-genome sequence of a classical Swine Fever virus isolated from the uttarakhand state of India.

We report the first complete genome sequence of a classical swine fever (CSF) virus of subgenotype 2.2. The virus (CSFV/IND/UK/LAL-290) was isolated from the Uttarakhand state of India from a backyard pig suspected of having CSF.
