Abstract
Environmental heat stress in dairy cattle leads to poor health, reduced milk production and decreased reproductive efficiency. Multiple genes interact and coordinate the response to overcome the impact of heat stress. The present study identified heat shock regulated genes in the peripheral blood mononuclear cells (PBMC). Genome-wide expression patterns for cellular stress response were compared between two genetically distinct groups of cattle viz., Hariana (B. indicus) and Vrindavani (B. indicus X B. taurus). In addition to major heat shock response genes, oxidative stress and immune response genes were also found to be affected by heat stress. Heat shock proteins such as HSPH1, HSPB8, FKB4, DNAJ4 and SERPINH1 were up-regulated at higher fold change in Vrindavani compared to Hariana cattle. The oxidative stress response genes (HMOX1, BNIP3, RHOB and VEGFA) and immune response genes (FSOB, GADD45B and JUN) were up-regulated in Vrindavani whereas the same were down-regulated in Hariana cattle. The enrichment analysis of dysregulated genes revealed the biological functions and signaling pathways that were affected by heat stress. Overall, these results show distinct cellular responses to heat stress in two different genetic groups of cattle. This also highlight the long-term adaptation of B. indicus (Hariana) to tropical climate as compared to the crossbred (Vrindavani) with mixed genetic makeup (B. indicus X B. taurus).

Abstract
Foot-and-mouth disease (FMD) is a major disease of livestock in India and causes huge economic losses. The formal FMD control program started in 2003–04 in selected districts and was gradually expanded. The present study provides a descriptive review of the FMD outbreaks, prevalent serotypes, and genetic and antigenic features of the FMD virus (FMDV) that circulated in the country between 2011 and 2020. FMD outbreaks were regularly reported in cloven-hoofed domestic livestock and wildlife, with three serotypes including O, A, and Asia1. During the study period, a total of 2226 FMD outbreaks were documented and serotypes confirmed. FMDV serotype O dominated the outbreak scenario, accounting for about 92% of all outbreaks, followed by Asia1 (5% of all outbreaks) and A (3% of all outbreaks). Two major epidemics of FMD on an unprecedented scale during the years 2013 and 2018 by serotype O were recorded. The spatial distribution of FMD was characterized by a larger number of outbreaks in the southern region of the country. In an annual-scale analysis, 2020 was the year with the lowest outbreaks, and 2013 was the year with the highest. The month-scale analysis showed that outbreaks were reported throughout the year, with the highest numbers between October and March. The emergence of three major lineages (O/ME-SA/Ind2001d, O/ME-SA/Ind2001e, and O/ME-SA/Ind2018) of serotype O was observed during the period. In the cases of serotype A and Asia1, the appearance of at least one novel lineage/genetic group, including A/G-18/non-deletion/2019 and Asia1/Group-IX, was documented. While serotype A showed the advent of antigenic variants, serotypes O and Asia1 did not show any antigenic diversity. It was noticed during the course of an outbreak that animal movement contributes significantly to disease transmission. Except for 2018, when numerous FMD outbreaks were recorded, the number of annual outbreaks reported after 2016 has been lower than in the first half of the decade, probably due to mass vaccination and COVID-19 pandemic-linked movement restrictions. Even during outbreaks, disease symptoms in ruminant populations, including cattle, were found to be less severe. Regular six-monthly immunization certainly has a positive impact on the reduction of disease burden and should be followed without fail and delay, along with intensive disease surveillance.

Abstract
The study aimed to explore the serum levels of HSP70 and identify its possible association with serum cortisol, thyroid hormones, and acute-phase protein concentrations in cattle naturally infected with foot-and-mouth disease (FMD) virus. After the FMD outbreak in an organized dairy cattle farm in India, blood samples were obtained from clinically infected (n = 40) and apparently healthy (n = 30) animals. Samples were processed and tested by an in-house DIVA assay for confirmation of FMD infection. Serum was analyzed for HSP70, cortisol, T4, T3, haptoglobin, and serum amyloid A by enzyme-linked immunosorbent assay (ELISA). HSP70 concentrations were significantly higher in the serum of clinically infected cattle (p < 0.01) than the healthy group. To the best of our knowledge, this is the first report describing the elevated serum levels of HSP70 under infectious diseases of bovines. Cortisol (p < 0.05), haptoglobin (p < 0.001), and serum amyloid A (p < 0.05) concentrations also markedly increased in the diseased animals; however, no differences (p > 0.05) were found in T4 and T3 levels between healthy and infected cattle. Elevated HSP70 concentration correlated positively with high cortisol (p < 0.05) and haptoglobin (p < 0.001) levels suggesting an essential link between these acute events during clinical infectious phase of FMD.

Abstract
Here, we studied the in vivo expression of Th1 (IL2 and IFN gamma) and Th2 (IL4 and IL10) - cytokines and antiviral molecules - IRF3 and ISG15 in peripheral blood mononuclear cells in relation to antigen and antibody dynamics under Peste des petits ruminants virus (PPRV) vaccination, infection and challenge in both sheep and goats. Vaccinated goats were seropositive by 9 days post vaccination (dpv) while in sheep idiosyncratic response was observed between 9 and 14 dpv for different animals. Expression of PPRV N gene was not detected in PBMCs of vaccinated and vaccinated challenged groups of both species, but was detected in unvaccinated infected PBMCs at 9 and 14 days post infection. The higher viral load at 9 dpi coincided with the peak clinical signs of the disease. The peak in viral replication at 9 dpi correlated with significant expression of antiviral molecules IRF3, ISG15 and IFN gamma in both the species. With the progression of disease, the decrease in N gene expression also correlated with the decrease in expression of IRF3, ISG15 and IFN gamma. In the unvaccinated infected animals ISG15, IRF3, IFN gamma and IL10 expression was higher than vaccinated animals. The IFN gamma expression predominated over IL4 in both vaccinated and infected animals with the infected exhibiting a stronger Th1 response. The persistent upregulation of this antiviral molecular signature - ISG15 and IRF3 even after 2 weeks post vaccination, presumably reflects the ongoing stimulation of innate immune cells.

Abstract
Bluetongue is an economically important infectious, arthropod borne viral disease of domestic and wild ruminants, caused by Bluetongue virus (BTV). Sheep are considered the most susceptible hosts, while cattle, buffalo and goats serve as reservoirs. The viral pathogenesis of BTV resulting in presence or absence of clinical disease among different hosts is not clearly understood. In the present study, transcriptome of sheep and goats peripheral blood mononuclear cells infected with BTV-16 was explored. The differentially expressed genes (DEGs) identified were found to be significantly enriched for immune system processes - NFκB signaling, MAPK signaling, Ras signaling, NOD signaling, RIG signaling, TNF signaling, TLR signaling, JAK-STAT signaling and VEGF signaling pathways. Greater numbers of DEGs were found to be involved in immune system processes in goats than in sheep. Interestingly, the DEHC (differentially expressed highly connected) gene network was found to be dense in goats than in sheep. Majority of the DEHC genes in the network were upregulated in goats but down-regulated in sheep. The network of differentially expressed immune genes with the other genes further confirmed these findings. Interferon stimulated genes - IFIT1 (ISG56), IFIT2 (ISG54) and IFIT3 (ISG60) responsible for antiviral state in the host were found to be upregulated in both the species. STAT2 was the TF commonly identified to co-regulate the DEGs, with its network showing genes that are downregulated in sheep but upregulated in goats. The genes dysregulated and the networks perturbed in the present study indicate host variability with a positive shift in immune response to BTV in goats than in sheep.

Abstract
Systems biology is an interdisciplinary research field in life sciences, which involves a comprehensive and quantitative analysis of the interactions between all of the components of biological systems over time. For the past 50 years the discipline of virology has overly focused on the pathogen itself. However, we now know that the host response is equally or more important in defining the eventual pathological outcome of infection. Systems biology has in recent years been increasingly recognised for its importance to infectious disease research. Host-virus interactions can be better understood by taking into account the dynamical molecular networks that constitute a biological system. To decipher the pathobiological mechanisms of any disease requires a deep knowledge of how multiple and concurrent signal-transduction pathways operate and are deregulated. Hence the intricacies of signalling pathways can be dissected only by system level approaches. Deciphering the host virus interactions through system biology approach reviewed High throughput techniques to understand the host pathogen interactions examined Shift from virus-centric perspective to spectrum of virus-host interactions Modeling of host-virus cross talk

Abstract
Bovine tropical theileriosis is an important haemoprotozoan disease associated with high rates of morbidity and mortality particularly in exotic and crossbred cattle. It is one of the major constraints of the livestock development programmes in India and Southeast Asia. Indigenous cattle (Bos indicus) are reported to be comparatively less affected than exotic and crossbred cattle. However, genetic basis of resistance to tropical theileriosis in indigenous cattle is not well documented. Recent studies incited an idea that differentially expressed genes in exotic and indigenous cattle play significant role in breed specific resistance to tropical theileriosis. The present study was designed to determine the global gene expression profile in peripheral blood mononuclear cells derived from indigenous (Tharparkar) and cross-bred cattle following in vitro infection of T. annulata (Parbhani strain). Two separate microarray experiments were carried out each for cross-bred and Tharparkar cattle. The cross-bred cattle showed 1082 differentially expressed genes (DEGs). Out of total DEGs, 597 genes were down-regulated and 485 were up-regulated. Their fold change varied from 2283.93 to -4816.02. Tharparkar cattle showed 875 differentially expressed genes including 451 down-regulated and 424 up-regulated. The fold change varied from 94.93 to -19.20. A subset of genes was validated by qRT-PCR and results were correlated well with microarray data indicating that microarray results provided an accurate report of transcript level. Functional annotation study of DEGs confirmed their involvement in various pathways including response to oxidative stress, immune system regulation, cell proliferation, cytoskeletal changes, kinases activity and apoptosis. Gene network analysis of these DEGs plays an important role to understand the interaction among genes. It is therefore, hypothesized that the different susceptibility to tropical theileriosis exhibited by indigenous and crossbred cattle is due to breed-specific differences in the dealing of infected cells with other immune cells, which ultimately influence the immune response responded against T. annulata infection.

Abstract
Hemagglutinin neuraminidase (HN) is a membrane protein of Newcastle disease virus (NDV) with the ability to induce apoptosis in many transformed cell lines. TNF-α is a multi-factorial protein that regulates cell survival, differentiation and apoptosis. In a previous study, we reported that HN protein induces apoptosis by downregulating NF-κB expression. Further, we speculated that downregulation of NF-κB expression might sensitize HeLa cells to TNF-α-mediated apoptosis. Therefore, the present study was undertaken to investigate if HN protein could sensitize HeLa cells to TNF-α and to examine the apoptotic potential of the HN protein and TNF-α in combination. The results revealed that the pro-apoptotic effects were more pronounced with the combination of HN and TNF-α than with HN or TNF-α alone, which indicates that the HN protein indeed sensitized the HeLa cells to TNF-α-induced cell death. The results of the study provide a mechanistic insight into the apoptotic action of HN protein along with TNF-α, which could be valuable in treating tumor types that are naturally resistant to TNF-α.

Abstract
BACKGROUND Many viral proteins exhibit selective cytotoxicity for tumor cells without affecting the normal diploid cells. The apoptin protein of chicken infectious anemia virus is one of such proteins, which has been shown to kill tumor cells specifically. However, an effective cancer treatment strategy also requires assistance from the immune system. Recently, poly (I:C) has been shown to be an effective cancer vaccine adjuvant. AIM In this study, we assessed the anti-tumor potential of apoptin gene transfer alone and in combination with poly (I:C) in a 4T1 mouse mammary tumor model. METHODS 4T1 cells were used to induce mammary tumor in Balb/c mice. Mice bearing tumors were divided into 6 groups, and each group received six intratumoral injections during a period of one month. After the last immunization, the animals were sacrificed, and peripheral blood, spleen, lungs, liver, heart, kidney and tumor tissues were collected for immunological, molecular and pathological analysis. RESULTS We report that intratumoral administration of apoptin plasmid along with poly (I:C) not only significantly inhibited the growth of mammary tumor, but also induced a potent anti-tumor immune response as indicated by the increase in blood CD4+, CD8+ cells and infiltration of immune cells in the tumor tissue. Further, blood serum analysis of the cytokines revealed increased secretion of Th1 cytokines (IFN-γ and IL-2). CONCLUSIONS The results of our study demonstrate that the inclusion of poly (I:C) significantly enhanced the anti-tumor activity of apoptin mainly by inducing a potent anti-tumor immune response. Therefore, we report the use of apoptin and poly (I:C) combination as a novel and powerful strategy for cancer immunotherapy.

Abstract
Newcastle Disease (ND) is one of the major causes of economic loss in the poultry industry. Newcastle Disease Virus (NDV) is a single-stranded, negative-sense enveloped RNA virus (Fam. Paramyxoviridae; Order Mononegavirales). In the present study three monoclonal antibodies (MAbs) were produced by polyethyleneglycol (PEG)-mediated fusion of lymphocytes sensitized to NDV Bareilly strain and myeloma cells. NDV possesses ability to agglutinate erythrocytes of avian species. All the three MAbs designated as 2H7, 3E9 and 3G6 caused hemagglutination inhibition of NDV by specifically binding to NDV. The reactivity for all the 3 MAbs on indirect ELISA was found to be significantly higher than the antibody and antigen controls. On flowcytometry of HeLa cells infected with NDV using the MAbs as primary antibodies, there was a significant difference in the percentage of cells showing positive fluorescence compared to the mock control. One of the MAbs (3E9) was found to react with hemagglutinin-neuraminidase (HN) protein on western blot.

Abstract
The non-structural protein (NS1) of parvoviruses plays an important role in viral replication and is thought to be responsible for inducing cell death. However, the detailed mechanism and the pathways involved in canine parvovirus type 2 NS1 (CPV2.NS1) induced apoptosis are not yet known. In the present study, we report that expression of CPV2.NS1 in HeLa cells arrests cells in G1 phase of the cell cycle and the apoptosis is mitochondria mediated as indicated by mitochondrial depolarization, release of cytochrome-c and activation of caspase 9. Treatment of cells with caspase 9 inhibitor Z-LEHD-FMK reduced the induction of apoptosis significantly. We also report that expression of CPV2.NS1 causes accumulation of reactive oxygen species (ROS) and treatment with an antioxidant reduces the ROS levels and the extent of apoptosis. Our results provide an insight into the mechanism of CPV2.NS1 induced apoptosis, which might prove valuable in developing NS1 protein as an oncolytic agent.

Abstract
Viral gene oncotherapy, targeted killing of cancer cells by viral genes, is an emerging non-infectious therapeutic cancer treatment modality. Chemo and radiotherapy in cancer treatment is limited due to their genotoxic side effects on healthy cells and need of functional p53, which is mutated in most of the cancers. VP3 (apoptin) of chicken infectious anaemia (CIA) and NS1 (Non structural protein 1) of Canine Parvovirus-2 (CPV-2) have been proven to have oncolytic potential in our laboratory. To evaluate oncolytic potential of VP3 and NS1 together these genes needed to be cloned in a bicistronic vector. In this study, both these genes were cloned and characterized for expression of their gene products and its apoptotic potential. The expression of VP3 and NS1 was studied by confocal microscopy and flowcytometry. Expression of VP3 and NS1 in pVIVO.VP3.NS1 transfected HeLa cells in comparison to mock transfected cells indicated that the double gene construct expresses both the products. This was further confirmed by flowcytometry where there was increase in cells expressing VP3 and NS1 in pVIVO.VP3.NS1 transfected group in comparison with the mock control group. The apoptotic inducing potential of this characterized pVIVO.VP3.NS1 was evaluated in human cervical cancer cell line (HeLa) by DNA fragmentation assay, TUNEL assay and Hoechst staning. This double construct was observed to induce apoptosis in HeLa cells.

Abstract
The use of viruses for treatment of cancer overcomes the bottlenecks of chemotherapy and radiotherapy. Several viruses and their proteins have been evaluated for oncolytic effect. The VP3 protein (apoptin) of chicken anemia virus is one such protein with an inherent ability to lyse cancer and transformed cells while leaving normal cells unharmed. In the present study, the apoptosis inducing potential of VP3 protein of CAV was evaluated in human cervical cancer cell line (HeLa). It was found that in VP3-induced apoptosis, caspase-dependent intrinsic pathway plays an important role with the cleavage of poly (ADP-ribose) polymerase (PARP) and there was no evidence of involvement of death receptor-mediated extrinsic pathway. The results of this study provide intuitive information and strengthen the candidacy of apoptin as a viral oncotherapeutic agent.

Abstract
Peste des petits ruminants (PPR), is an acute transboundary viral disease of economic importance, affecting goats and sheep. Mass vaccination programs around the world resulted in the decline of PPR outbreaks. Sungri 96 is a live attenuated vaccine, widely used in Northern India against PPR. This vaccine virus, isolated from goat works efficiently both in sheep and goat. Global gene expression changes under PPR vaccine virus infection are not yet well defined. Therefore, in this study we investigated the host-vaccine virus interactions by infecting the peripheral blood mononuclear cells isolated from goat with PPRV (Sungri 96 vaccine virus), to quantify the global changes in the transcriptomic signature by RNA-sequencing. Viral genome of Sungri 96 vaccine virus was assembled from the PPRV infected transcriptome confirming the infection and demonstrating the feasibility of building a complete non-host genome from the blood transcriptome. Comparison of infected transcriptome with control transcriptome revealed 985 differentially expressed genes. Functional analysis showed enrichment of immune regulatory pathways under PPRV infection. Key genes involved in immune system regulation, spliceosomal and apoptotic pathways were identified to be dysregulated. Network analysis revealed that the protein - protein interaction network among differentially expressed genes is significantly disrupted in infected state. Several genes encoding TFs that govern immune regulatory pathways were identified to co-regulate the differentially expressed genes. These data provide insights into the host - PPRV vaccine virus interactome for the first time. Our findings suggested dysregulation of immune regulatory pathways and genes encoding Transcription Factors (TFs) that govern these pathways in response to viral infection.

Abstract
Many viruses have the ability to modulate the apoptosis, and to accomplish it; viruses encode proteins which specifically interact with the cellular signaling pathways. While some viruses encode proteins, which inhibit the apoptosis or death of the infected cells, there are viruses whose encoded proteins can kill the infected cells by multiple mechanisms, including apoptosis. A particular class of these viruses has specific gene(s) in their genomes which, upon ectopic expression, can kill the tumor cells selectively without affecting the normal cells. These genes and their encoded products have demonstrated great potential to be developed as novel anticancer therapeutic agents which can specifically target and kill the cancer cells leaving the normal cells unharmed. In this review, we will discuss about the viral genes having specific cancer cell killing properties, what is known about their functioning, signaling pathways and their therapeutic applications as anticancer agents.

Abstract
The canine parvovirus type 2 (CPV-2) causes an acute disease in dogs. It has been found to induce cell cycle arrest and DNA damage leading to cellular lysis. In this paper, we evaluated the apoptotic potential of the "new CPV-2a" in MDCK cells and elucidated the mechanism of the induction of apoptosis. The exposure of MDCK cells to the virus was found to trigger apoptotic response. Apoptosis was confirmed by phosphatidylserine translocation, DNA fragmentation assays, and cell cycle analysis. Activation of caspases-3, -8, -9, and -12 and decrease in mitochondrial potential in CPV-2a-infected MDCK cells suggested that the CPV-2a-induced apoptosis is caspase dependent involving extrinsic, intrinsic, and endoplasmic reticulum pathways. Increase in p53 and Bax/Bcl2 ratio was also observed in CPV-2a-infected cells.

Abstract
Apoptosis is programmed cell death that normally occurs during development and aging in multicellular animals. Apoptosis also occurs as a defense mechanism against disease or harmful external agents. It can be initiated by a variety of stimuli including viruses and viral proteins. Canine parvovirus type 2 (CPV-2) that causes acute disease in dogs has been found to induce cell cycle arrest and DNA damage leading to cellular lysis. Though non structural protein 1 (NS1) of many parvoviruses has been found to be apoptotic, no report on the apoptotic potential of NS1 of CPV-2 (CPV-2.NS1) exists. In this study, we evaluated the apoptotic potential of CPV-2.NS1 in HeLa cells. CPV-2.NS1 has been found to induce apoptosis which was evident through characteristic DNA fragmentation, increase in hypodiploid cell count, phosphatidyl serine translocation and activation of caspase-3. Increase in caspase-3 activity and no change in p53 activity with time in CPV-2.NS1 expressing HeLa cells showed the induction of apoptosis to be caspase dependent and p53 independent.

Abstract
Viral gene oncotherapy is emerging as a biotherapeutic cancer treatment modality based on targeted killing of cancer cells by viral genes. Newcastle disease virus (NDV) has the property to cause selective oncolysis of tumor cells sparing normal cells. NDV has a single stranded negative sense RNA genome, which is 15,186 nucleotide long and consists of six genes, which codes for eight proteins. NDV like other paramyxoviruses has the ability to generate multiple proteins from the P gene. P protein is encoded by an unedited transcript of the P gene, whereas the V and W protein are the results of RNA editing event in which one and two G residues are inserted at a conserved editing site within the P gene mRNA resulting in V and W transcripts, respectively. Although NDV is known to cause oncolysis by triggering apoptosis, the role of different viral proteins in selective oncolysis is still unclear. P gene edited products are known for its anti-apoptotic property in homologous host. In the present study, NDV P gene and its RNA edited products were amplified, cloned, sequenced and in vitro expression was done in HeLa cells. Further constructs were assayed for their apoptosis inducing ability in HeLa cells. Preliminary study suggested that P, V and W proteins are not apoptotic to HeLa cells.

Abstract
The canine Parvovirus 2, non-structural 1 (NS1) is a novel candidate tumor suppressor gene. To confirm the expression of the NS1 in HeLa cells after transfection there was a need to raise antiserum against CPV2- NS1. Therefore, this study was carried out to express and purify the recombinant NS1 (rNS1), and characterize the polyclonal serum. CPV2-NS1, complete coding sequence (CDS) was amplified, cloned in pET32a+ and expressed in BL21 (DE3) (pLysS). SDS-PAGE analysis revealed that the expression of the recombinant protein was maximum when induced with 1.5 mM IPTG. The 6 x His tagged fusion protein was purified on Ni-NTA resin under denaturing conditions and confirmed by western blot using CPV2 specific antiserum. The rabbits were immunized with the purified rNS1 to raise anti-NS1 polyclonal antiserum. The polyclonal serum was tested for specificity and used for confirming the expression of NS1 in HeLa transfected with pcDNA.cpv2.ns1 by indirect fluorescent antibody test (IFAT), flow cytometry and western blot. The polyclonal antiserum against NS1 could be very useful to establish functional in vitro assays to explore role of NS1 in cancer therapeutics.

The 6xHis-tagged fusion protein was purified on Ni-NTA and confirmed by Western blot using CAV specific antiserum. Rabbits were immunized with purified rVP3 to raise anti-VP3 polyclonal antibodies. Polyclonal serum was tested for specificity and used for confirming expression of VP3 in HeLa cells transfected with pcDNA.cav.vp3 by indirect fluorescent antibody test (IFAT), flow cytometry and Western blot. Available purified rVP3 and polyclonal antibodies against VP3 may be useful to understand its functions which may lead to application of VP3 in cancer therapeutics.

Abstract
Parvoviruses are small, 260-A-diameter, icosahedral, non-enveloped, single-stranded DNA viruses with a genome of approximately 5 kb. Non structural protein, (NS-1) is especially relevant, being both essential for virus replication and the main factor responsible for virus pathogenicity and cytotoxicity. This protein has also been reported to possess the property of killing of transformed cells. The present study was carried out to clone, characterize and express the NS-1 gene of canine parvovirus. NS-1 complete CDS 2020bp was amplified, cloned into eukaryotic expression vector pcDNA 3.1(+), sequenced and characterized by in vitro expression analysis. Functional activity of recombinant construct, pcDNA.cpv.NS-1, was evaluated by RT-PCR and flow cytometry for the expression of NS-1 specific mRNA and NS-1 protein, respectively, in transfected HeLa cells. This recombinant plasmid may serve as an important tool to evaluate the apoptotic potential of NS-1 protein of canine parvovirus in cultured HeLa cells.

Abstract
Newcastle disease (ND) is highly contagious, economically important viral disease affecting most of avian species worldwide. Newcastle disease virus (NDV) has single stranded negative sense RNA genome which encodes for six structural and two non-structural proteins. Envelope glycoproteins i.e. hemagglutinin-neuraminidase (HN) and the fusion (F), elicit protective immune response. In this study, HN and F genes of velogenic (virulent) strain were amplified and cloned at multiple cloning sites A and B, respectively into pIRES bicistronic vector for use as bivalent DNA vaccine against ND. The recombinant plasmid was characterized for its orientation by restriction enzyme digestion and PCR. Expression of HN and F genes was assessed in transfected Vero cells at RNA level using RT-PCR in total RNA as well as protein level using IFAT, IPT and western blot using NDV specific antiserum. All these experiments confirmed that HN and F genes cloned in recombinant pIRES.nd.hn.f are functionally active. The recombinant construct is being evaluated as DNA vaccine against ND.

Abstract
Granulocyte-macrophage colony stimulating factor (GMCSF), a multifunctional cytokine can enhance immune responses when administered along with DNA vaccine. Aim of the present study was to clone and express the chicken GMCSF cytokine for use as 'genetic adjuvant'. Chicken GMCSF gene 435bp was amplified using specific primers in which restriction sites of BamHI and HindIII were at forward and reverse primers respectively. The PCR product was cloned into eukaryotic expression vector pcDNA 3.1(+) and clones were confirmed by restriction digestion and nucleotide sequencing. Functional activity of recombinant GMCSF was checked by expression of GMCSF specific mRNA in transfected Vero cells by RT-PCR of total RNA isolated from transfected Vero cells. The recombinant plasmid can be used as genetic adjuvant in chicken.
