Dab tsi yog cov tshuaj glucagon thiab cov tshuaj glucagon
Cov glucagon "tshaib plab" yog qhov paub me ntsis hauv kev sib piv nrog insulin, txawm hais tias ob yam yeeb tshuaj no ua haujlwm nyob rau hauv cov khoom sib txuas thiab ua lub luag haujlwm tseem ceeb hauv peb lub cev. Glucagon yog ib qho ntawm cov tshuaj hormones tseem ceeb ntawm tus txiav, uas, ua ke nrog insulin, yog lub luag haujlwm rau kev tswj ntshav hauv cov ntshav qabzib. Kev npaj tshuaj hormones raws li nws tau nquag siv hauv kev kho mob rau kev rov qab los ntawm mob ntshav qab zib mellitus thiab kev npaj rau kev kuaj mob txoj hnyuv.
Tus qauv thiab synthesis ntawm glucagon
Glucagon hu ua txawv, tab sis feem ntau nws tau txiav txim siab raws li kev xav - cov tshuaj insulin antagonist. Cov kws tshawb fawb H. Kimball thiab J. Murlin tau tshawb pom ib yam khoom tshiab nyob rau hauv lub txiav caj dab hauv xyoo 1923, 2 xyoos tom qab tshawb pom keeb kwm ntawm insulin. Tab sis tom qab ntawd, ob peb tus neeg paub txog lub luag haujlwm tsis cuam tshuam ntawm glucagon hauv lub cev.
Niaj hnub no hauv cov tshuaj, 2 lub luag haujlwm tseem ceeb ntawm "kev tshaib plab hormone" yog siv - hyperglycemic thiab kuaj mob, txawm hais tias qhov tseeb cov tshuaj muaj ntau yam haujlwm tseem ceeb hauv lub cev tam sim ntawd.
Glucagon yog protein ntau, ntau qhov tseeb, peptide hormone hauv nws cov qauv tshuaj. Los ntawm cov qauv, nws yog ib txoj saw polypeptide muaj 29 amino acids. Nws yog tsim los ntawm preproglucagon, ib qho tseem muaj zog tshaj polypeptide uas suav nrog 180 amino acids.
Txawm hais tias qhov tseem ceeb ntawm glucagon hauv lub cev, nws cov qauv amino acid yog qhov yooj yim heev, thiab yog tias peb siv lus science, nws yog "txhawm rau txhawm rau". Yog li, tib neeg, nyuj, npua thiab nas, cov qauv ntawm cov tshuaj no yog qhov zoo ib yam. Yog li no, glucagon npaj feem ntau tau txais los ntawm txoj kev mob siab ntawm tus heev nyuj los yog npua.
Kev khiav dej num thiab cuam tshuam ntawm glucagon hauv lub cev
Kev zais cia ntawm glucagon tshwm sim nyob rau hauv endocrine ib feem ntawm tus txiav hauv qab lub npe hu ua "islets of Langerhans." Thib tsib ntawm cov islets no tshwj xeeb alpha cell uas tsim cov keeb.
3 yam cuam tshuam rau glucagon ntau lawm:
- Qhov siab ntawm cov piam thaj hauv cov ntshav (kev poob qis hauv cov ntshav qab zib mus rau ib qho tseem ceeb tuaj yeem ua rau qhov nce ntawm ob peb npaug ntawm cov "tshaib plab" hauv ntshav).
- Kev nce ntxiv ntawm cov amino acids nyob rau hauv cov ntshav, tshwj xeeb yog alanine thiab arginine.
- Kev siv dag zog lub cev (kev qhia tawm ntawm lub peev xwm ntawm qhov muaj peev xwm ntawm tib neeg muaj peev xwm nce qhov kev ua rau cov tshuaj hormones ntau dua 4-5 zaug).
Ib zaug hauv cov ntshav, "kev tshaib kev nqhis" ua rau cov neeg mob siab, ua kom txoj hlua khi rau lawv thiab txhawb cov kua nplaum tawm hauv cov ntshav, tswj nws kom nyob tus yees. Tsis tas li, qhov tshuaj hormone glucagon ntawm tus txiav ua tiav cov haujlwm hauv lub cev:
- kev ua kom cov lipid tawg thiab cov ntshav cov roj uas txhaws taus
- txhim kho ntshav txaus hauv lub raum
- txhawb nqa kev nthuav dav sai ntawm sodium ntawm lub cev (thiab qhov no pab txoj kev ua haujlwm hauv lub plawv)
- kev koom tes hauv kev tsim dua tshiab ntawm cov qog hlwb
- stimulates tso tawm insulin los ntawm hlwb
Tsis tas li, glucagon yog qhov tseem ceeb uas tsis txaus ntseeg-nyob rau hauv caj npab ntawm adrenaline los muab kev tawm tsam ntawm lub cev "kev sib ntaus lossis ya davhlau". Thaum adrenaline tawm rau hauv cov ntshav, glucagon tsub kom cov piam thaj ntau yuav luag tau txhawm rau txhim kho cov leeg pob txha, thiab ua kom cov leeg muaj pa oxygen ntau dua.
Lub tshuab
| hloov kho codeTus txheej txheem ntawm kev ua ntawm glucagon yog vim nws txoj kev khi rau qee yam glucagon receptors uas lub siab ua haujlwm. Qhov no ua rau muaj kev nce G-protein-mediated adenylate cyclase kev ua haujlwm thiab qhov nce hauv cAMP tsim. Qhov tshwm sim yog nce catabolism ntawm glycogen tso rau hauv lub siab (glycogenolysis). qhov chaw tsis tau teev 2198 hnub Glucagon rau hepatocytes pabcuam raws li cov cim qhia sab nraud txog qhov yuav tsum tau tso cov piam thaj rau hauv cov ntshav vim qhov tawg ntawm glycogen (glycogenolysis) lossis kev sib txuas ntawm cov piam thaj los ntawm lwm yam - gluconeogenesis. Cov tshuaj hormones khi rau cov receptor ntawm lub plasma membrane thiab ua kom adenylate cyclase, uas ua rau kev tsim cov cAMP los ntawm ATP, los ntawm G-protein. Hauv qab no yog qhov tsis txaus ntawm kev coj ua hauv lub siab ua rau glycogen phosphorylase thiab kev cuam tshuam ntawm glycogen synthase. Qhov txheej txheem no ua rau muaj kev tso tawm glucose-1-phosphate los ntawm glycogen, uas hloov mus rau cov piam thaj-6-phosphate. Tom qab ntawd, nyob rau hauv qab ntawm qabzib-6-phosphatase, cov piam thaj dawb yog tsim, uas tuaj yeem tawm ntawm cov cell mus rau hauv cov ntshav. Yog li, glucagon nyob rau hauv daim siab, txhawb kev zom zom ntawm glycogen, pab tswj cov piam thaj hauv cov ntshav ntawm ib theem. Glucagon tseem ua rau gluconeogenesis, lipolysis, thiab ketogenesis nyob hauv lub siab.
Glucagon tau siv tsis muaj qhov cuam tshuam rau lub glycogen ntawm cov pob txha pob txha, thaj vim tias qhov tsis muaj qhov yuav luag tiav ntawm glucagon receptors hauv lawv. Glucagon ua rau muaj kev nce ntxiv hauv cov insulin secretion los ntawm kev noj qab haus huv ntawm pancreatic cells-cells thiab kev cuam tshuam ntawm insulinase. Qhov no yog, thaj, ib qho ntawm kev tsim kho lub cev ntawm kev tiv thaiv kab mob glucagon hob hyperglycemia.
Glucagon muaj qhov muaj zog inotropic thiab chronotropic rau lub myocardium vim muaj ntau qhov kev tsim ntawm cAMP (uas yog, nws muaj cov nyhuv zoo ib yam li cov haujlwm ntawm β-adrenergic receptor agonists, tab sis tsis muaj kev cuam tshuam β-adrenergic hauv qhov tseeb ntawm cov nyhuv no). Qhov tshwm sim yog qhov nce ntawm cov ntshav siab, ib qho kev nce siab hauv lub zaus thiab lub zog ntawm kev mob plawv.
Hauv qhov siab, glucagon ua rau lub zog antispasmodic zoo, so ntawm cov leeg ntawm cov khoom nruab nrog sab hauv, tshwj xeeb cov hnyuv, tsis yog kho kom haum los ntawm adenylate cyclase.
Glucagon koom nrog hauv kev siv ntawm "kev ntaus lossis khiav" kev cuam tshuam, ua kom muaj qhov muaj zog ntawm lub zog ntxiv (tshwj xeeb, qabzib, cov roj dawb, keto acids) rau cov leeg pob txha thiab nce cov ntshav mus rau cov leeg pob txha los ntawm kev txhim kho lub luag haujlwm ntawm lub plawv. Tsis tas li ntawd, glucagon tsub kom lub zais ntawm catecholamines los ntawm adrenal medulla thiab ua rau kev cuam tshuam ntawm cov ntaub so ntswg ntau dua rau catecholamines, uas tseem nyiam qhov ua kom tiav ntawm "ntaus lossis khiav" cov tshuaj tiv thaiv.

Glucagon thiab Metabolism
Qhov kev txiav ua tiav rau ob peb txoj haujlwm. Exocrine muaj hauv kev tsim cov kua txiv zom, uas yog tawm los ntawm cov hlab mus rau hauv duodenum 12. Kev ua haujlwm ntawm endocrine yog qhov ntau lawm thiab tso tawm ncaj qha rau cov roj ntsha ntawm polypeptides thiab cov tshuaj hormones: insulin, glucagon, somatostatin, ghrelin thiab lwm tus. Cov tshuaj ua ke ntawm cov tshuaj no nyob hauv cov islet of Langerhans, cov haujlwm tau muab faib ua ob peb hom hlwb. Glucagon yog tsim los ntawm a-cov hlwb; lawv muaj kwv yees li 20% ntawm tag nrho cov naj npawb ntawm cov hlwb hauv pancreatic islets.
Glucagon hais txog polypeptide cov tshuaj hormones, nws cuam tshuam rau txhua hom metabolism. Lub luag haujlwm tseem ceeb ntawm glucagon yog dab tawm tsam:
Hom metabolism | Glucagon nkaus | Cov tshuaj insulin |
Carbohydrate | Nce glycemia. Txhawm rau ua qhov no, nws pab txhawb glycogenolysis (rov qab tawg ntawm glycogen rau piam thaj) thiab gluconeogenesis (kev sib txuas ntawm cov piam thaj hauv lub cev), inhibits kev ua haujlwm ntawm insulin. | Nws txo cov glycemia, cuam tshuam los ntawm ob peb sab: nws txhawb cov ntshav qabzib xa mus rau cov nqaij mos, ua kom nws tawg, pab txhim kho cov piam thaj hauv cov ntawv glycogen, thiab tiv thaiv kev tsim cov piam thaj hauv lub cev. |
Lipid | Txhawb nqa kev rhuav tshem ntawm cov rog thiab nws siv nyiaj rau cov txheej txheem hauv lub zog, ua rau muaj kev nce siab ntxiv ntawm ketone lub cev hauv cov ntshav. | Tsim kho qhov tsim ntawm cov nqaij tshiab adipose. |
Kev Cuam Tshuam | Muaj cov nyhuv catabolic. | Cov tshuaj hormones ua ib qho anabolic: nws txhawb cov leeg nce siab. |
Hauv cov neeg muaj kev noj qab haus huv, cov ntshav qabzib hloov me ntsis, tom qab noj mov nws yuav rov qab zoo li qub. Kev cai ntawm glycemia yog cov txheej txheem nyuaj, uas suav nrog lub hlwb, lub plab hnyuv, cov leeg, qog pituitary, lub qog thiab tus txiav, ob lub raum, nplooj siab thiab lwm yam plab hnyuv siab raum. Raws li qhov tshwm sim ntawm lawv cov kev ua haujlwm ua ke, cov qib zoo ntawm cov piam thaj rau cov metabolism yog tswj hwm.
Lub cev ua kom sib haum
Yog tias cov piam thaj hauv ntshav poob vim yog ua haujlwm hauv lub cev lossis tsis muaj zaub mov noj, glucagon synthesis nce siab. Yuav muaj dab tsi tshwm sim thaum ua qhov no:
- Glycogen khw muag khoom noj uas tiv thaiv lub siab yog qhib kom ua haujlwm. Glycogen lov, raug pov rau hauv cov ntshav hauv daim ntawv ntawm cov piam thaj, glycemia normalizes. Cov nyhuv ntawm glucagon tsis siv rau glycogen tso rau hauv cov leeg nqaij.
- Lub siab pib ua haujlwm ntxiv cov piam thaj los ntawm pyruvate thiab lwm yam khoom uas tsis yog carbohydrate.
