TGF\u03b2-2, a constituent of the ocular microenvironment, converts conventional APCs that are pulsed with Ag into cells that induce immune deviation when injected into naive mice. TGF\u03b2-2-treated APCs under-express IL-12 and CD40, and over-express active TGF\u03b2. We have examined transcriptional changes within macrophage hybridoma no. 59, which promotes Th1 cell differentiation, and TGF\u03b2-2-treated no. 59 as well as macrophage hybridoma no. 63, both of which induce immune deviation similar to anterior chamber-associated immune deviation. Immune deviation-inducing hybridomas up-regulated expression of thrombospondin, TGF\u03b2, IFN-\u03b1 and \u03b2, murine macrophage elastase, and macrophage-inflammatory protein-2 genes, while down-regulating expression of the genes for NF-\u03baB and CD40. Based on the known properties of these gene products, a model is proposed in which these gene products, alone and through interacting signaling pathways, confer upon conventional APCs the capacity to create and surround themselves with an immunomodulatory microenvironment. The model proposes that the pleiotropic effects of thrombospondin are primarily responsible for creating this microenvironment that is stabile, rich in active TGF\u03b2 and IFN-\u03b1 and \u03b2, deficient in IL-12, and chemoattractant via macrophage-inflammatory protein-2 for NK T cells. It is further proposed that presentation of Ag to T cells in this microenvironment leads to their differentiation into regulatory cells that suppress Th1 cell-dependent immunogenic inflammation.<\/jats:p>","DOI":"10.4049\/jimmunol.168.5.2264","type":"journal-article","created":{"date-parts":[[2014,4,22]],"date-time":"2014-04-22T03:53:38Z","timestamp":1398138818000},"page":"2264-2273","source":"Crossref","is-referenced-by-count":48,"title":["Expression of Thrombospondin in TGF\u03b2-Treated APCs and Its Relevance to Their Immune Deviation-Promoting Properties"],"prefix":"10.1093","volume":"168","author":[{"given":"Sharmila","family":"Masli","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Schepens Eye Research Institute, Harvard Medical School , Boston, MA 02114"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruce","family":"Turpie","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Schepens Eye Research Institute, Harvard Medical School , Boston, MA 02114"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karl H","family":"Hecker","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Schepens Eye Research Institute, Harvard Medical School , Boston, MA 02114"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J Wayne","family":"Streilein","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Schepens Eye Research Institute, Harvard Medical School , Boston, MA 02114"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2002,3,1]]},"reference":[{"key":"2025032712345139800_R1","first-page":"1121","volume-title":"J.
