Local cytokine transcription in naïve and previously infected sheep and lambs following challenge with Teladorsagia circumcincta
BACKGROUND The abomasal helminth Teladorsagia circumcincta is one of the most economically important parasites affecting sheep in temperate regions. Infection is particularly detrimental to lambs, in which it can cause pronounced morbidity and severe production losses. Due to the spreading resistance of this parasite to all classes of anthelmintic drugs, teladorsagiosis is having an increasingl...
متن کاملPlasma paraoxonase, sphingosine-1-phosphate, total sialic acid, and heat shock protein-27 in the liver of the sheep naturally infected with Cysticercus tenuicollis: Evidence on pathological changes
The present study aimed to investigate whether sphingosine 1 phosphate (S1P), paraoxonase (PON), total sialic acid (TSA), and heat shock protein-27 (HSP27) are altered in the sheep during infection of the liver with Cysticercus tenuicollis. This study was conducted on40 healthy sheep and40 sheep with Cysticercus tenuicollis infection. The infected and non-infected animals were selected based on...
متن کاملShort Communication: Some Observations on the Role of Bradykinin in Immunity to Teladorsagia circumcincta in Sheep
Bradykinin is a physiologically active peptide involved in vasodilation and smooth muscle contraction and is previously shown to be increased in gastrointestinal mucus during nematode challenge in sheep. Here, it is shown that bradykinin in the abomasum is positively correlated with both mast cells and globule leukocytes in the abomasum, and that all three of these parameters are negatively ass...
متن کاملVariable exon usage of differentially-expressed genes associated with resistance of sheep to Teladorsagia circumcincta
The resistance and susceptibility of sheep to the common abomasal nematode parasite, Teladorsagia circumcincta is strongly associated with the differential polarization of the immune response. Resistant animals control larval colonization by the production of a protective antibody response regulated by Th2 T cells. Susceptible sheep respond to infection by developing an inflammatory Th1/Th17 re...
متن کاملProteomic approach to identify candidate effector molecules during the in vitro immune exclusion of infective Teladorsagia circumcincta in the abomasum of sheep.
In the present study we have employed an in vitro organ challenge model to study the post-challenge responses in parasite naïve and immune gastric tissue of sheep, in an attempt to identify the host derived factors involved in immune exclusion of Teladorsagia circumcincta larvae. Proteins present in the epithelial cells and mucus from ovine abomasa following parasite challenge in previously naï...
