We previously showed that MK aggravates experimental autoimmune encephalomyelitis (EAE) by decreasing regulatory CD4+CD25+Foxp3+ T cells (Tregs), a population that regulates the development of autoimmune responses, although the precise mechanism remains uncertain. In this article, we show that MK produced in inflammatory conditions suppresses the development of tolerogenic dendritic cells (DCregs), which drive the development of inducible Treg. MK suppressed DCreg-mediated expansion of the CD4+CD25+Foxp3+ Treg population. DCregs expressed significantly higher levels of CD45RB and produced significantly less IL-12 compared with conventional dendritic cells. However, MK downregulated CD45RB expression and induced IL-12 production by reducing phosphorylated STAT3 levels via src homology region 2 domain-containing phosphatase-2 in DCreg. Inhibiting MK activity with anti-MK RNA aptamers, which bind to the targeted protein to suppress the function of the protein, increased the numbers of CD11clowCD45RB+ dendritic cells and Tregs in the draining lymph nodes and suppressed the severity of EAE, an animal model of multiple sclerosis. Our results also demonstrated that MK was produced by inflammatory cells, in particular, CD4+ T cells under inflammatory conditions. Taken together, these results suggest that MK aggravates EAE by suppressing DCreg development, thereby impairing the Treg population. Thus, MK is a promising therapeutic target for various autoimmune diseases.<\/jats:p>","DOI":"10.4049\/jimmunol.1102346","type":"journal-article","created":{"date-parts":[[2012,2,9]],"date-time":"2012-02-09T12:13:30Z","timestamp":1328789610000},"page":"2602-2611","source":"Crossref","is-referenced-by-count":44,"title":["Midkine Inhibits Inducible Regulatory T Cell Differentiation by Suppressing the Development of Tolerogenic Dendritic Cells"],"prefix":"10.1093","volume":"188","author":[{"given":"Yoshifumi","family":"Sonobe","sequence":"first","affiliation":[{"name":"Department of Neuroimmunology, Research Institute of Environmental Medicine, Nagoya University , Nagoya 464-8601 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hua","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Neuroimmunology, Research Institute of Environmental Medicine, Nagoya University , Nagoya 464-8601 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shijie","family":"Jin","sequence":"additional","affiliation":[{"name":"Department of Neuroimmunology, Research Institute of Environmental Medicine, Nagoya University , Nagoya 464-8601 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Kishida","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Nagoya University Graduate School of Medicine , Nagoya 466-8550 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Kadomatsu","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Nagoya University Graduate School of Medicine , Nagoya 466-8550 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideyuki","family":"Takeuchi","sequence":"additional","affiliation":[{"name":"Department of Neuroimmunology, Research Institute of Environmental Medicine, Nagoya University , Nagoya 464-8601 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuya","family":"Mizuno","sequence":"additional","affiliation":[{"name":"Department of Neuroimmunology, Research Institute of Environmental Medicine, Nagoya University , Nagoya 464-8601 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akio","family":"Suzumura","sequence":"additional","affiliation":[{"name":"Department of Neuroimmunology, Research Institute of Environmental Medicine, Nagoya University , Nagoya 464-8601 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2012,3,15]]},"reference":[{"key":"2025032409592591600_r1","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1016\/j.it.2007.10.006","article-title":"Regulatory CD4 T cells: sensing the environment","volume":"29","author":"Matarese","year":"2008","journal-title":"Trends Immunol."},{"key":"2025032409592591600_r2","doi-asserted-by":"crossref","first-page":"749","DOI":"10.1016\/j.jaci.2009.03.001","article-title":"Therapeutic approaches to allergy and autoimmunity based on Foxp3+ regulatory T-cell activation and expansion","volume":"123","author":"Miyara","year":"2009","journal-title":"J.
