Lub olfactory system yog ib qho tseem ceeb ntawm lub paj hlwb thiab tseem yog ib qho ntawm cov kev xav ntxov tshaj plaws uas tshwm sim hauv cov tsiaj evolution. Smell plays lub luag haujlwm tseem ceeb hauv ob qho tib si tsiaj ciaj sia thiab tib neeg lub neej. Kev ua haujlwm ntawm olfactory yog ze rau ntau yam kab mob, xws li cov neeg mob qaug dab peg qee zaum ntsib olfactory hallucinations ua ntej qaug dab peg; Cov neeg uas thaum chiv keeb los hnov tsw tom qab muaj qhov tsis hnov tsw tsw, uas tej zaum yuav muaj feem xyuam rau Parkinson's los yog Alzheimer's kab mob.Muaj pov thawj txaus los ua pov thawj tias kev ua haujlwm ntawm VIP interneurons hauv lub hlwb yog qhov tseem ceeb rau kev ua kom olfactation, thiab tus yuam sij rau txoj kev tshawb no yog yuav ua li cas rov qab ua haujlwm ntawm lub hlwb.VIP Peptide hmoovthiab VIP interneurons.
1.Dab tsi yog cov kev tshawb fawb txog kev tswj hwm ntawm VIP neurons ntawm lub zos olfactory neural circuits thiab olfactory muaj nuj nqi?
Kev kawm txog cov txheej txheem kev nkag siab ntawm olfactory thiab olfactory muaj nuj nqi tuaj yeem tsis tsuas yog nthuav tawm cov qauv kev ua haujlwm ntawm olfactory system nws tus kheej, tab sis kuj muab cov ntaub ntawv tseem ceeb rau cov kab mob thiab kev kuaj mob ntxov ntawm qee yam kab mob. Lub olfactory noob yog thawj qhov chaw rau olfactory cov ntaub ntawv kis tau tus mob, thiab nws complex neural circuits yuav extract thiab integrate olfactory cov ntaub ntawv los ntawm olfactory neurons, thiab ua complex ntaub ntawv ua thiab coj encoding. M / Ts yog ob hom projection neurons nyob rau hauv lub olfactory noob, thiab ntau hom interneurons nyob rau hauv lub olfactory noob ua lub luag hauj lwm tseem ceeb nyob rau hauv regulating cov zis ntawm M / Ts, ntawm uas muaj coob tus VIP interneurons faib nyob rau hauv lub txheej reticular txheej. thiab kev saib xyuas ntawm kev nco hauv cov txheej txheem coj cwj pwm. Txawm li cas los xij, lawv lub luag haujlwm hauv kev tswj hwm olfactory paj hlwb thiab sawv cev rau cov ntaub ntawv olfactory tsis tau kawm.
2.Lub luag hauj lwm ntawm VIP interneurons nyob rau hauv cov kev cai ntawm olfactory paj circuits thiab cov sawv cev ntawm olfactory ntaub ntawv yog dab tsi?
Cov kws tshawb fawb thawj zaug tau piav qhia txog kev faib tawm thiab electrophysiological yam ntxwv ntawm VIP neurons nyob rau hauv lub olfactory noob, uas qhia tau hais tias VIP neurons feem ntau faib nyob rau hauv lub txheej reticular txheej thiab glomerular txheej (Daim duab 1A); Ib yam li lwm cov txheej txheej sab nraud ntawm cov neurons, VIP neurons tau txais cov khoom siv neural excitatory los ntawm Sangha hlwb (Daim duab 1BC). Cov txiaj ntsig ntawm fiber ntau optic calcium kaw tau pom tias VIP neurons nthuav tawm cov lus teb rau cov ntxhiab tsw (Daim duab 1D). Txhawm rau tshawb xyuas lub luag haujlwm ntawm VIP neurons hauv kev sawv cev ntawm cov ntaub ntawv olfactory, cov kws tshawb fawb tau ua ke lub taub hau txhim kho hauv vivo electrophysiological kaw tshuab thiab optogenetic thev naus laus zis los kawm txog qhov cuam tshuam ntawm kev ua kom VIP neurons ntawm M / Ts hluav taws xob ua haujlwm ntawm olfactory noob tawm cov neurons thiab thaj chaw muaj peev xwm (LFP) ntawm lub qhov muag olfactory. Cov txiaj ntsig tau pom tias photoactivation ntawm VIP neurons inhibited spontaneous M / Ts hluav taws xob ua haujlwm (Daim duab 2A); Cov ntxhiab tsw tuaj yeem ua rau muaj kev ntxhov siab thiab cuam tshuam cov lus teb hauv M / Ts, thaum photoactivation ntawm VIP neurons inhibits tsw induced excitatory thiab inhibitory teb (Daim duab 2B). Cov khoom siv hluav taws xob muab cov ntaub ntawv tseem ceeb rau kev sawv cev thiab kev nkag siab ntawm cov ntaub ntawv olfactory ntawm tib- theem ntawm tes, thaum LFP tuaj yeem cuam tshuam cov kab hluav taws xob hauv zos ntawm lub teeb pom kev zoo thiab kev ua haujlwm thiab kev sib koom ua ke ntawm cov ntaub ntawv ntawm lub teeb olfactory thiab lwm thaj chaw hauv lub hlwb. LFP oscillations nyob rau hauv lub olfactory noob, tshwj xeeb tshaj yog beta oscillations thiab siab gamma oscillations, pom muaj zog thiab ruaj khov teb rau odors thiab ua lub luag hauj lwm tseem ceeb nyob rau hauv kev tshawb nrhiav tsw. Teb cov ntaub ntawv muaj peev xwm qhia tau tias ua kom VIP neurons suppresses tsw induced beta thiab siab gamma oscillations. Cov txiaj ntsig no qhia tias VIP neurons ua lub luag haujlwm tseem ceeb hauv kev sawv cev ntawm cov ntaub ntawv olfactory.
3.Puas VIP neurons puas cuam tshuam rau tus cwj pwm olfactory?
Cov txiaj ntsig ntawm vivo electrophysiological kev tshawb fawb qhia tias VIP neurons tsim inhibitory synaptic kev sib txuas nrog olfactory noob tawm cov neurons (M / Ts). Txhawm rau txheeb xyuas qhov kev sim no, cov kws tshawb fawb tau tshawb xyuas ntxiv txog kev tswj xyuas cov txiaj ntsig ntawm VIP neurons ntawm olfactory noob hlwb siv ex vivo patch clamp txheej txheem. Cov kev tshawb fawb tau pom tias, tsis zoo li cov nyhuv disinhibition ntawm VIP neurons nyob rau hauv lub cortex, VIP neurons nyob rau hauv lub olfactory noob ncaj qha inhibit Sangha hlwb los ntawm tso GABA neurotransmitters (Daim duab 3).
Txij li thaum VIP neurons tuaj yeem cuam tshuam cov hluav taws xob ua haujlwm ntawm olfactory noob tawm cov neurons thiab cuam tshuam rau cov sawv cev ntawm cov ntaub ntawv olfactory, VIP neurons puas cuam tshuam rau tus cwj pwm olfactory? Cov kws tshawb fawb tau siv tshuaj genetic txoj kev los ua kom tsis muaj VIP neurons nyob rau hauv lub qhov muag olfactory thiab kuaj olfactory ntsig txog tus cwj pwm ntawm tus cwj pwm. Cov txiaj ntsig kev tshawb fawb pom tau hais tias kev tsis ua haujlwm VIP neurons txo qhov kev kuaj pom thiab kev daws teeb meem ntawm cov nas, tab sis tsis cuam tshuam rau qhov kev nyiam ntawm lub cev thiab tus cwj pwm aversion.
4.Yuav ua li cas ua kom rov qab los ntawm VIP neurons?
Txoj kev tshawb no qhia txog cov yam ntxwv tseem ceeb ntawm cov chav kawm ntawm interneurons dav faib rau sab nrauv reticular thiab glomerular txheej ntawm olfactory noob - vasoactive plab hnyuv peptide expressing (VIP) neurons - thiab lawv cov synaptic kev sib txuas nrog olfactory noob tso zis neurons - cov hlwb thiab cov hlwb tseem ceeb nyob rau hauv olfactory ntsig txog tus cwj pwm. Txawm li cas los xij, neurons hauv tib neeg lub cev tseem tuag nrog kev laus, thiab Vasoactive Intendal Peptide neurons tsis muaj qhov tshwj xeeb. Yog li cov kws tshawb fawb tau cog lusVasoactive Intesting Peptide hmoovrau hauv cov nas ntawm cov hnub nyoog sib txawv thiab tseem pom tias VIP neurons tuaj yeem qhib tau rau hauv txoj kev tsim nyog.
