e have set up an

ex vivo

ovine abomasal model, which can mimic the multicellular process to explore the early steps

in haemonchine nematode infection using RNA-seq technology. Ovine abomasal explants were collected for histological

and transcriptional analysis, supernatants collected to quantitate lactate dehydrogenase (LDH) enzymes. A total of 233 were

substantially induced genes between L4-inoculated and uninoculated-control tissues, respectively. However, a total of 14

were considerably down-regulated genes between the 51 aforementioned tissues. Fifteen pathways were annotated by Kyoto

Encyclopedia of Genes, and Genomes pathway analysis accounted for the significant percentage in immediate response to

larval-stage of

H. contortus

. Key genes up-regulated in response to the addition of L4-inoculum of

H. contortus

were IL-6, IL-8,

C1q, atypical chemokine receptor-3, chemokine ligand-2, manganese superoxide dismutase, integrin alpha-7, -8, -9 , integrin

subunit beta-1, integrin subunit beta 6, intercellular adhesion molecule-1 and actin alpha-1. This study shows for the first time

that galectin-1 is up-regulated in an

ex-vivo

abomasal segment model exposed to L4-inoculum of

H. contortus

following 6 h of

incubation. The abomasal segment model has been shown to be a suitable tool to study the haemonchine larval-stage effects on

the ovine abomasal tissues prior to

in vivo

assessment
