The retina-specific basigin isoform does not induce IL-6 expression in mouse monocytes.
Purpose: Basigin gene products are positioned on adjacent cell types in the neural retina and are thought to compose a lactate metabolon important for photoreceptor cell function. The Ig0 domain of basigin isoform 1 (basigin-1) is highly conserved throughout evolution, which suggests a conserved function. It has been suggested that the Ig0 domain has proinflammatory properties, and it is hypothesized to interact with basigin isoform 2 (basigin-2) for cell adhesion and lactate metabolon formation. Therefore, the purpose of the present study was to determine whether the Ig0 domain of basigin-1 binds to basigin-2 and whether the region of the domain used for binding is also used to stimulate interleukin-6 (IL-6) expression.
Methods: Binding was assessed using recombinant proteins corresponding to the Ig0 domain of basigin-1 and endogenously expressed basigin-2 from mouse neural retina and brain protein lysates. The proinflammatory properties of the Ig0 domain were analyzed with exposure of the recombinant proteins to the mouse monocyte RAW 264.7 cell line and subsequent measurement of the IL-6 concentration in the culture medium via enzyme-linked immunosorbent assay (ELISA).
Results: The data indicate that the Ig0 domain interacts with basigin-2 through a region within the amino half of the domain and that the Ig0 domain does not stimulate the expression of IL-6 in mouse cells in vitro.
Conclusions: The Ig0 domain of basigin-1 binds to basigin-2 in vitro. In addition, contrary to previous reports, there was no evidence that the Ig0 domain potentiates IL-6 expression in a mouse monocyte cell line in vitro. However, it is possible that the Ig0 domain stimulates the expression of proinflammatory cytokines other than IL-6, or that the potential involvement of the Ig0 domain of basigin-1 in the acute inflammatory response is dependent on species.
期刊介绍：
Molecular Vision is a peer-reviewed journal dedicated to the dissemination of research results in molecular biology, cell biology, and the genetics of the visual system (ocular and cortical).
Molecular Vision publishes articles presenting original research that has not previously been published and comprehensive articles reviewing the current status of a particular field or topic. Submissions to Molecular Vision are subjected to rigorous peer review. Molecular Vision does NOT publish preprints.
For authors, Molecular Vision provides a rapid means of communicating important results. Access to Molecular Vision is free and unrestricted, allowing the widest possible audience for your article. Digital publishing allows you to use color images freely (and without fees). Additionally, you may publish animations, sounds, or other supplementary information that clarifies or supports your article. Each of the authors of an article may also list an electronic mail address (which will be updated upon request) to give interested readers easy access to authors.
