Zusammenfassung: | Lumpy skin disease (LSD) is a notifiable re-emerging transboundary viral disease of bovines that inflicts heavy losses in affected livestock farms. Genetic variations contribute substantially to the inter-individual differences in the immune response against disease agents. The present study aimed to evaluate the genetic basis of differential immune response in Vrindavani cattle by comparing the hematological, biochemical and cytokine genes’ expression profiles of LSD-affected and unaffected animals. After 21 days of the outbreak at the farm, the animals were grouped as affected (those who developed symptoms) and unaffected/healthy (those who did not). Standard hematological and biochemical parameters were evaluated in both the groups. Expression profiling of important
Th1
(IL2, INFG and GMCSF) and
Th2
(IL4, IL6 and IL10) cytokines was also performed via a relative quantification approach using real-time PCR. Erythrogram and leucogram analyses revealed significant differences in total leucocyte count (TLC: 14.18 ± 0.74 versus 11.38 ± 0.68 x10
3
/µL), hemoglobin (Hb: 8.66 ± 0.42 versus 10.84 ± 0.17 g%) and percentage of neutrophils (46.40 ± 1.98 versus 35.40 ± 2.11%), lymphocytes (49.40 ± 1.99 versus 62.40 ± 1.86) and monocytes (4.20 ± 0.37 versus 2.40 ± 0.40) between the affected and healthy animals, respectively. The production of liver enzymes (SGOT and SGPT) was significantly higher in affected animals (74.18 ± 4.76 and 59.51 ± 2.75) when compared to the healthy counterparts (65.95 ± 9.18 and 39.21 ± 3.31). The expression profiling of
Th1
and
Th2
cytokines revealed significant differences between the two groups, except IL10. The expression of IL2, GMCSF and IL6 were upregulated in healthy animals while that of INFG, IL4 and IL10 were upregulated in LSD-affected animals. The highest abundance was observed for IL2 transcripts in healthy animals among all assessed cytokines with log
2
fold change of 1.61 as compared to affected counterparts. Overall, the immune response in healthy animals (after exposure to LSD virus) was predominated by the expression of
Th1
cell proliferation and there was an increased production of pro-inflammatory cytokines as compared to the affected counterparts. The results revealed that the effective immune response to LSD in cattle consists of changes in hematological and biochemical parameters and altered expression profile of cytokines with enhanced phagocytosis and lymphocyte recruitment. Furthermore, optimal expression of
