Development and comparison of in vivo and in vitro models for endometritis in cows and mares.

Abstract: In order to investigate pathogenic mechanisms of acute endometritis in cows and mares, we established an in vivo model in both species. Based on the results of an in vitro transmigration system, human recombinant interleukin-8 (rhIL-8; 1.25 microg per mare and 5 microg per cow in 50 ml phosphate-buffered saline) was used to attract polymorphonuclear neutrophil granulocytes (PMNs) into the uteri. Peak numbers of uterine neutrophils were attracted after 6h, in both cows and mares. On average, mares responded more sensitively than cows, with 15 times higher numbers of rhIL-8-attracted uterine neutrophils (72+/-8 x 10(7)cells). In contrast to in vitro studies, in vivo migrated neutrophils (uterine neutrophils) of both species displayed a significantly reduced MHC class I expression. Expression of the CD11a molecule was significantly enhanced on equine uterine neutrophils but downregulated on bovine cells. Compared with untreated autologous peripheral neutrophils, both uterine and in vitro migrated neutrophils showed no alteration of phagocytic capacity. The ability to generate reactive oxygen species (ROS) was significantly upregulated in bovine and equine uterine neutrophils. This was also observed after in vitro migration of equine neutrophils, whereas ROS generation by bovine neutrophils was significantly depressed. In summary, the concept of inducing endometritis directly by local application of human interleukin-8 has been reliably successful in cows and mares. The model permits the analysis of PMN migration into the uterus under defined and controlled conditions. The observed differences between cows and mares with respect to phenotypical and functional characteristics of in vivo attracted uterine cells point to species-related features of neutrophil migration. In vitro transmigrated bovine and equine cells partially differ in phenotype and function from uterine neutrophils. Therefore, the in vitro transmigration assay cannot completely represent the in vivo endometritis model described here.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article concerns the development and comparison of in vivo and in vitro models for endometritis in cows and mares. The aim was to understand the mechanisms of acute endometritis in these animals. The study found differences in how cows and mares respond to the condition, and also noticed discrepancies between the in vivo and in vitro models.

Establishment of In Vivo Models

  • The researchers established an in vivo model for both cows and mares to study acute endometritis, which is inflammation of the inner lining of the uterus.
  • Human recombinant interleukin-8 (rhIL-8), an agent known to attract immune cells called polymorphonuclear neutrophil granulocytes (PMNs), was introduced into the UTI to study how these cells respond in the uterus environment. The rhIL-8 dosage was specified depending on the species (1.25 micrograms for mares and 5 micrograms for cows).
  • Both cows and mares exhibited peak numbers of UTI neutrophils after 6 hours. It was observed that mares were more sensitive than cows, with 15 times higher neutrophil count.

Neutrophil Characteristics

  • In contrast with in vitro studies, in vivo migrated neutrophils of both cows and mares showed significantly reduced MHC class I expression.
  • Differentiation was observed in the expression of the CD11a molecule between the two species; it was enhanced in equine uterine neutrophils but downregulated in bovine cells.
  • Both the uterine and in vitro migrated neutrophils displayed no change in their capacity to engulf and digest particles (phagocytic capacity).
  • The ability to generate reactive oxygen species (ROS) was significantly upregulated in uterine neutrophils of both species. However, in the case of in vitro migration, bovine neutrophils showed a significant depression in ROS generation.

Outcome and Implications

  • Overall, the in vivo model successfully induced endometritis in both cows and mares using human interleukin-8, allowing for the analysis of neutrophil migration into the uterus under controlled conditions.
  • The observed differences between cows and mares in terms of immune response to affliction point to species-related features of neutrophil migration.
  • The researchers concluded that the in vitro migration model doesn’t completely represent the in vivo endometritis model because of observable differences in the appearance and function of the migrated cells in the two situations.
