They have uncovered new details about the process through which motor neurons develop into subtypes that connect the spinal cord with different target muscles and help to control different body parts.<\/p>\n<p>Led by biologists at the University at Buffalo, the research concludes that a gene called Kdm6b helps control motor neurons&#8217; fate. The study, which was completed in mice, finds that Kdm6b:<\/p>\n<ul>\n<li>Encourages motor neurons to develop into subtypes found in the <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>l motor column. These neurons target dorsal axial muscles.<\/li>\n<li>Encourages motor neurons to develop into subtypes found in the hypaxial motor column. These neurons target intercostal and abdominal muscles.<\/li>\n<li>Discourages motor neurons from developing into subtypes found in the lateral motor column. These neurons target ventral and dorsal limb muscles.<\/li>\n<li>Discourages motor neurons from developing into subtypes found in the preganglionic motor column identities. These neurons target the sympathetic ganglia, which control internal organs, such as the heart.<\/li>\n<\/ul>\n<p>The study also reports that Kdm6b works cooperatively with a complex of proteins called Isl1-Lhx3 to influence the way motor neurons diversify.<\/p>\n<p>&#8220;During early development, humans generate nerve cells that connect with muscles and control muscle activity,&#8221; says UB biologist Soo-Kyung Lee, the study&#8217;s senior author. &#8220;The formation of these nerve cells at the right time and place is critical for humans&#8217; survival and movement controls. Our study in mice revealed how these nerve cells acquire their specialized identity. Our study could inform strategies to generate specialized nerve cells and treat motor system disorders and spinal cord injuries.&#8221;<\/p>\n<p>Lee, Ph.D., is Empire Innovation Professor and Om P.

Lee. &#8220;Our paper provides a crucial insight into this important topic, making a major contribution to understanding how motor neurons further develop to different columnar clusters.&#8221;\n                                                                                                                        <\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                                                                        Study identifies diverse spectrum of neurons that govern movement\n                                                                                    <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Wenxian Wang et al, The histone demethylase Kdm6b regulates subtype diversification of mouse spinal motor neurons during development, <i>Nature Communications<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"http:\/\/dx.doi.org\/10.1038\/s41467-022-28636-7\">DOI: 10.1038\/s41467-022-28636-7<\/a><\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    University at Buffalo<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.buffalo.edu\/\"><br \/>\n                                                        <svg>\n                                                            <use href=\"https:\/\/medx.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n                                                        <\/svg><br \/>\n                                                    <\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                 <strong>Citation<\/strong>:<br \/>\n                                                 How motor neurons develop into subtypes that activate different muscles (2022, February 17)<br \/>\n                                                 retrieved 17 February 2022<br \/>\n                                                 from https:\/\/medicalxpress.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-02-motor-neurons-subtypes-muscles.html<\/p>\n<p>                                            This document is subject to copyright.
