Trosolwg
Rwy'n niwrowyddonydd sy'n arbenigo yn y mecanweithiau biolegol sy'n sail i anhwylderau niwro-ddatblygiadol a niwroseiciatrig, gan gynnwys anhwylder sbectrwm awtistiaeth (ASD), anabledd deallusol, sgitsoffrenia, ac anhwylderau hwyliau. Mae fy ymchwil yn canolbwyntio ar ddeall sut mae ffactorau risg genetig yn tarfu ar ddatblygiad a swyddogaeth yr ymennydd, gyda'r nod o nodi targedau therapiwtig newydd.
Yn fy labordy, rydym yn defnyddio bôn-gelloedd pluripotent sy'n deillio o gleifion (iPSCs) i fodelu datblygiad ymennydd dynol in vitro. Trwy wahaniaethu'r celloedd hyn yn llinellau niwral ac organoidau ymennydd 3D, rydym yn ymchwilio i fecanweithiau clefyd ar y lefel gellog a moleciwlaidd.
Mae ein gwaith yn cael ei yrru gan ddull amlddisgyblaethol, gan integreiddio technegau cellog, genetig, electroffisiolegol, ymddygiadol a gwyddor deunyddiau i astudio cychwyn a dilyniant clefydau. Yn y pen draw, ein nod yw datgelu targedau cyffuriau dibynadwy a all lywio strategaethau therapiwtig yn y dyfodol ar gyfer anhwylderau cymhleth yr ymennydd.

Ymchwil
Trosolwg o Ymchwil
Mae anhwylderau niwroddatblygiadol a seiciatrig gan gynnwys anhwylder sbectrwm awtistiaeth (ASD), anabledd deallusol, a sgitsoffrenia yn gyflyrau cymhleth, ac yn aml yn wanhau gyda chanlyniadau cymdeithasol, emosiynol ac economaidd dwfn. Mae datblygiadau diweddar mewn geneteg wedi nodi mwtaniadau risg uchel a newidiadau cromosomaidd mewn loci gan gynnwys 1q21.1, 3q29, a 16p11.2, sy'n cynyddu'n sylweddol sensitifrwydd i'r anhwylderau hyn trwy gydol y cyfnod oes.
Er gwaethaf y darganfyddiadau hyn, mae'r mecanweithiau y mae'r ffactorau risg genetig hyn yn tarfu ar ddatblygiad a swyddogaeth yr ymennydd yn parhau i gael eu deall yn wael. Nod fy ymchwil yw datgelu sail niwrobiolegol risg genetig yn yr anhwylderau hyn, gyda'r nod terfynol o nodi targedau cyffuriau newydd ar gyfer ymyriadau therapiwtig yn y dyfodol.
Amcanion Ymchwil Cyfredol
1. Sail Niwral a Moleciwlaidd Microcephaly a Macrocephaly: Rydym yn astudio annormaleddau maint yr ymennydd sy'n gysylltiedig ag amrywiadau rhif copi 1q21.1 (CNVs), gan ganolbwyntio ar enynnau fel HYDIN2 a NOTCH2NL. Gan ddefnyddio organoidau cortical sy'n deillio o iPSC o unigolion â dileu neu ddyblygu 1q21.1, rydym yn ymchwilio i ddiffygion mewn pensaernïaeth cortical, amlhau niwral, a gwahaniaethu.
2. Mecanweithiau Newidiadau Mater Gwyn mewn Anhwylderau Niwroddatblygiadol: Gan ddefnyddio modelau bôn-gelloedd 2D a 3D o myelination datblygiadol, rydym yn archwilio sut mae CNVs 16p11.2 - sy'n gysylltiedig ag awtistiaeth a chyflyrau seiciatrig - yn tarfu ar uniondeb mater gwyn. Ein nod yw diffinio'r mecanweithiau cellog a moleciwlaidd sy'n sail i myelination wedi'i newid yn ystod datblygiad cynnar yr ymennydd.
3. Cyfraniad Niwrollid i Ddatblygiad yr Ymennydd: Rydym yn archwilio sut mae amlygiad llidiol amenedigol yn rhyngweithio â ffactorau risg genetig i newid trajectories niwro-ddatblygiadol. Gan ddefnyddio astrocytes a microglia sy'n deillio o iPSC o unigolion â CNVs risg uchel, rydym yn asesu newidiadau mewn signalau llidiol a'u heffaith ar swyddogaeth niwronau.
