Themâu Ymchwil : Niwrowyddoniaeth, Endocrinoleg a Geneteg
Mae gen i ddiddordeb yn y mecanweithiau genetig, endocrin ac imiwnolegol sy'n sail i wahaniaethau rhyw yn swyddogaeth yr ymennydd, ymddygiad a ffisioleg. Mae fy ngwaith yn canolbwyntio ar rôl genynnau ar y cromosomau rhyw (h.y. yr X ac Y), sy'n cael eu hetifeddu'n anghymesur rhwng y rhywiau: mae menywod yn etifeddu dau gromosom X (un o bob rhiant), tra bod dynion yn etifeddu un cromosom X (yn ddieithriad gan eu mam) a chromosom Y gan eu tad. Prif amcanion fy ymchwil yw: a) deall pam mae'r rhywiau yn wahanol agored i gyflyrau niwroddatblygiadol, seiciatrig a meddygol, b) deall yr anhwylderau seicolegol sy'n sail i pathoffisioleg sy'n gysylltiedig â beichiogrwydd a genedigaeth, ac c) i helpu i ddatblygu therapïau rhywiol mwy effeithiol. Mae gen i ddiddordeb hefyd mewn iechyd meddwl a chorfforol mewn cyflyrau croen (yn enwedig ichthyosis sy'n gysylltiedig ag X), ac rwy'n gweithio gyda sefydliadau'r trydydd sector yn genedlaethol ac yn rhyngwladol (e.e. Ichthyosis Support Group UK a Foundation for Ichthyosis and Related Skin Types (FIRST))
Fel Swyddog Meinwe Dynol yr Ysgol Seicoleg, ac yn aelod o Bwyllgor Llywodraethu Ymchwil Meinwe Dynol y Brifysgol, rwy'n gyfrifol am sicrhau bod unrhyw ymchwil sy'n cynnwys samplau meinwe dynol yn cael ei gynnal yn gyfreithlon. Rwyf hefyd yn gynrychiolydd yr Ysgol Seicoleg ar Banel Lles Anifeiliaid ac Ymchwil y Brifysgol (AWARP). Yn MEDIC, rwy'n Arweinydd ar gyfer rhaglen INSPIRE, cynllun a redir gan yr Academi Gwyddorau Meddygol i annog myfyrwyr meddygol, deintyddiaeth a milfeddygol israddedig i gymryd rhan mewn gweithgareddau ymchwil.
Crynodeb lleoliad
Rwyf wedi fy lleoli yn yr Ysgolion Seicoleg (PSYCH) a Meddygaeth (MEDIC) ym Mhrifysgol Caerdydd . Rwy'n aelod o'r Grŵp Geneteg Ymddygiadol (PSYCH/MEDIC), y Ganolfan Geneteg a Genomeg Niwroseiciatrig (MEDIC), yr Is-adran Meddygaeth Seicolegol a Niwrowyddorau Clinigol (MEDIC) a'r Sefydliad Arloesi Niwrowyddoniaeth ac Iechyd Meddwl (PSYCH/MEDIC).

Pynciau ymchwil a phapurau cysylltiedig
Mae ein gwaith yn defnyddio amrywiaeth eang o dechnegau arbrofol gan gynnwys: profion gweithredol a digymell o ymddygiad mewn cnofilod, dadansoddiad anatomegol a biocemegol o feinweoedd y corff, profion mynegiant genynnau a phrotein, mesur marcwyr endocrin, addasu/dadansoddi genetig a geneteg moleciwlaidd ddynol, profion niwroseicolegol, a dulliau arolwg ar-lein.
1. Rôl sylffatase steroid mewn ffenoteipiau ymennydd, ymddygiadol a ffisiolegol mewn dyn a llygoden
Mae ein gwaith blaenorol mewn llygod a bodau dynol wedi awgrymu y gall y genyn STS, sy'n amgodio'r ensym sy'n modiwleiddio niwrosteroidau sylffatase, ddylanwadu ar ystod eang o swyddogaethau ymddygiadol, gwybyddol a ffisiolegol, yn enwedig sylw a rhythm cardiaidd. Nod gwaith parhaus mewn modelau cnofilod a phoblogaethau clinigol yw pennu prosesau biolegol sy'n sensitif i effeithiau (dys)swyddogaeth steroid sylffatase, ac i egluro'r mecanweithiau niwrobiolegol y gall swyddogaeth sylffatase steroid effeithio ar wybyddiaeth. Mae'r gwaith hwn o berthnasedd uniongyrchol i'r anhwylder prin ichthyosis sy'n gysylltiedig â X (a achosir gan ddiffyg steroid sulfatase), a gall hefyd daflu goleuni ar y mecanweithiau sy'n sail i anhwylderau datblygiadol a chardiaidd idiopathig (e.e. ffibriliad atrïaidd) ac anhwylderau hwyliau ôl-enedigol.

2. Mecanweithiau genetig ac endocrinaidd sy'n sail i wahaniaethau rhyw yn natblygiad, ymddygiad a ffisioleg yr ymennydd
Mae benywod yn etifeddu dau gromosom X (un gan bob rhiant) tra bod gwrywod yn etifeddu un cromosom X (gan eu mam) a chromosom Y gan eu tad. Mae'r anghymesuredd hwn o etifeddiaeth ar draws y rhywiau yn arwain at dri phrif fecanwaith genetig a allai naill ai sail i wahaniaethau gwrywaidd-benywaidd mewn ffisioleg yn uniongyrchol, neu drwy effeithiau ar hormonau gan gynnwys androgenau ac estrogenau: i) mynegiant genynnau sy'n gysylltiedig ag Y mewn dynion yn unig (gan gynnwys y genyn sy'n pennu ceilliau SRY), ii) mynegiant uwch o enynnau sy'n gysylltiedig â X sy'n dianc rhag anactifadu X mewn meinweoedd benywaidd, a iii) mynegiant gwahaniaethol genynnau sy'n gysylltiedig â X sy'n destun y broses epigenetig-gyfryngol o argraffu genomig. Mae ein gwaith cydweithredol, mewn modelau cnofilod (e.e. model 39, llygoden XO a Four Core Genotypes ), mewn poblogaethau clinigol, ac mewn cyfranogwyr a meinweoedd iach yn anelu at ymchwilio i ba raddau a phenodoldeb y mae pob un o'r tri mecanwaith hyn yn cyfrannu at wahaniaethau rhyw mewn ffisioleg. Mae'r gwaith hwn yn debygol o lywio ein dealltwriaeth o'r pathoffisioleg foleciwlaidd sy'n sail i aneuploidies cromosom rhyw fel syndromau Turner a Klinefelter, ac anhwylderau niwroddatblygiadol sy'n rhagfarnu rhyw fel ADHD ac awtistiaeth.

3. Deall sail fiolegol risg anhwylder hwyliau ôl-enedigol
Gall mamau newydd gael eu heffeithio gan nifer o gyflyrau seiciatrig sy'n amrywio o ran difrifoldeb ac achosion. Mae gennym ddiddordeb arbennig mewn seicosis ôl-enedigol (PP), anhwylder seiciatrig prin ond hynod ddifrifol sy'n effeithio ar famau yn fuan ar ôl genedigaeth ac sy'n cael ei nodweddu gan delusions, newidiadau hwyliau, gorbryder a daddrefnu gwybyddol. Er gwaethaf ei ddifrifoldeb, mae'r niwrobioleg sy'n sail i'r risg PP yn cael ei ddeall yn wael iawn, yn rhannol o ganlyniad i beidio â chael modelau anifeiliaid addas ar gael. Nod ein gwaith mewn modelau cnofilod a phoblogaethau clinigol yw nodi a nodweddu llwybrau risg biolegol credadwy ar gyfer PP, yn y pen draw gyda'r bwriad o ddatblygu triniaethau gwell a biofarcwyr rhagfynegol.

4. Iechyd meddwl mewn cyflyrau croen
Yn dilyn ein gwaith mewn ichthyosis sy'n gysylltiedig ag X, rydym wedi dechrau ymchwilio i iechyd meddwl a ffenoteipiau ymddygiadol mewn cyflyrau croen eraill sydd â thueddiad genetig sylfaenol gan gynnwys ichthyosis vulgaris, psoriasis a chlefyd Darier.

5. Datblygu tasgau gwybyddiaeth cnofilod: deall gwahaniaethau rhyw mewn ymddygiad gamblo
Rydym wedi datblygu nifer o dasgau gweithredol newydd i asesu gwybyddiaeth mewn cnofilod, llawer ohonynt yn analogau tasgau niwroseicoleg a ddefnyddir i asesu gwybyddiaeth mewn bodau dynol, ac mae sawl un ohonynt bellach wedi'u haddasu i'w defnyddio gyda chyfarpar sgrin gyffwrdd i ganiatáu cyflwyniad ysgogiad soffistigedig. Ar hyn o bryd mae gennym ddiddordeb mewn defnyddio'r tasgau hyn i ddeall sail fiolegol rhagdueddiad gamblo, ac yn benodol, i ddeall pam mae cyffredinrwydd ymddygiad gamblo, a'r dilyniant i gamblo patholegol, yn wahanol rhwng dynion a menywod.

7. Ymchwilio i gysylltiadau rhwng trin system imiwnedd ac ymennydd ac ymddygiad
Mae llawer o anhwylderau seiciatrig a niwrolegol yn gysylltiedig â newidiadau yn swyddogaeth y system imiwnedd; fodd bynnag, mae'r cysylltiad rhwng newidiadau'r system imiwnedd a swyddogaeth ymennydd/ymddygiad yn dechrau cael ei egluro. Mae gennym ddiddordeb yn rôl math penodol o gell imiwnedd (celloedd-T rheoleiddiol, Tregs) ar yr ymennydd a'r ymddygiad. Mae Tregs yn imiwnosuppressive, a gallant hefyd ysgogi prosesau myelination - rydym yn amau y bydd eu disbyddu yn arwain at ffenoteipiau sy'n gysylltiedig ag anhwylderau hwyliau a seicotig (gan gynnwys yn y cyfnod ôl-enedigol), ac rydym yn defnyddio modelau llygoden i fynd i'r afael â'r rhagdybiaeth hon.

Diddordebau ymchwil ôl-raddedig
Mae gennym ddiddordeb mewn sut, a pham, mae'r rhywiau yn wahanol o ran swyddogaeth eu hymennydd, ymddygiad a ffisioleg. Mae gennym ddiddordeb arbennig mewn deall y mecanweithiau biolegol sy'n sail i'r risg o gyflyrau niwroddatblygiadol fel ADHD ac awtistiaeth (sy'n cael diagnosis llawer mwy aml mewn dynion na menywod) ac anhwylderau seiciatrig sy'n gysylltiedig â beichiogrwydd a genedigaeth fel seicosis ôl-enedigol, sy'n effeithio ar fenywod yn fuan ar ôl genedigaeth. Mae gennym ddiddordeb hefyd mewn penderfynyddion iechyd meddwl a chorfforol mewn unigolion â chyflyrau dermatolegol cynhenid.
Rydym yn defnyddio amrywiaeth eang o ddulliau arbrofol mewn modelau cnofilod ac mewn poblogaethau dynol iach a chlinigol, ac yn canolbwyntio'n benodol ar effeithiau ymennydd ac ymddygiadol genynnau ar y cromosomau rhyw (hy yr X ac Y) sydd wedi'u hetifeddu'n anghymesur rhwng dynion a menywod.
Efallai y bydd gan ein hastudiaethau oblygiadau pwysig ar gyfer deall pam mae dynion a menywod yn ymddwyn yn wahanol, o ran pam mae'r rhywiau yn agored i rai cyflyrau meddygol yn wahanol, ac ar gyfer datblygu therapïau a biofarcwyr mwy effeithiol sy'n benodol i ryw.
