Identity of the E-series prostaglandin produced by equine chondrocytes and synovial cells in response to a variety of stimuli.

This study aimed to identify the type of E-series prostaglandin, specifically PGE2, which is produced by equine cells when faced with an inflammatory stimulus. This was carried out using two radioimmunoassays.

Objective of the Research

• The main purpose of the study was to identify and characterize a specific E-series prostaglandin produced by horses’ cells following an inflammatory stimulus
• Given that an E-series prostaglandin was previously identified in equine inflammatory exudate, it was vital to confirm if the eicosanoid is indeed PGE2.

Methodology

• The researchers used two radioimmunoassays to identify the E-series prostaglandin.
• One of these assays was relatively non-specific for PGE2, while the other was more specific for PGE1. Both assays helped determine the specific type of E-series prostaglandin produced by the equine cells.

Findings

• The study was successful in confirming the identity of the E-series prostaglandin produced by equine chondrocytes and synovial cells following exposure to various stimuli as PGE2.
• This confirmation is significant because it conclusively identifies the E-series prostaglandin produced under these circumstances, which could have implications for understanding and treating inflammatory conditions in horses.
