Description:
Class I major histocompatibility complex (class I MHC) molecules, known to be important for immune responses to antigen, are expressed also by neurons that undergo activity-dependent, long-term structural and synaptic modifications. Here, we show that in mice genetically deficient for cell surface class I MHC or for a class I MHC receptor component, CD3zeta, refinement of connections between retina and central targets during development is incomplete. In the hippocampus of adult mutants, N-methyl-D-aspartate receptor-dependent long-term potentiation (LTP) is enhanced, and long-term depression (LTD) is absent. Specific class I MHC messenger RNAs are expressed by distinct mosaics of neurons, reflecting a potential for diverse neuronal functions. These results demonstrate an important role for these molecules in the activity-dependent remodeling and plasticity of connections in the developing and mature mammalian central nervous system (CNS).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2175035/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2175035/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huh, G S -- Boulanger, L M -- Du, H -- Riquelme, P A -- Brotz, T M -- Shatz, C J -- 1F32EY07016/EY/NEI NIH HHS/ -- EY06912/EY/NEI NIH HHS/ -- F32 EY007016/EY/NEI NIH HHS/ -- F32 EY007016-02/EY/NEI NIH HHS/ -- F32 EY007016-03/EY/NEI NIH HHS/ -- MH48108/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2000 Dec 15;290(5499):2155-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, 220 Longwood Avenue, Boston, MA 02115, USA. gshuh@alum.mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11118151" target="_blank"〉PubMed〈/a〉
