Osteoporosis bụ ọrịa skeletal sistemu nke ọtụtụ ihe na-emekarị nke ọkpụkpụ ọkpụkpụ dị ala na mmebi microarchitectural nke ọkpụkpụ ọkpụkpụ. Nke a na-eduga n'ịbawanye ọkpụkpụ ọkpụkpụ na ike ịdaba na mgbaji, na mgbaji úkwù na ọkpụkpụ azụ bụ ihe a na-emekarị. Ọ na-emetụta ndụ ndị ọrịa nke ukwuu ma na-abawanye nkwarụ na ọnụ ọgụgụ ọnwụ. Site na ọnụ ọgụgụ ndị ịka nká zuru ụwa ọnụ na-arịwanye elu, ọnụ ọgụgụ osteoporosis na-aga n'ihu na-arị elu.

Ọgwụgwọ osteoporosis ọdịnala, dị ka bisphosphonates na nhọrọ ndị na-anabata estrogen receptor modulators (SERMs), bụ isi na-edobe njupụta nke ọkpụkpụ site n'igbochi ọkpụkpụ osteoclast-mediated resorption. Otú ọ dị, arụmọrụ ha dị oke maka ndị ọrịa nwere oke ọkpụkpụ na-ebelata nke ukwuu na ihe ize ndụ mgbaji. Ọ bụ ezie na parathyroid hormone (PTH) 1-34 iberibe (teriparatide) bụ onye ọrụ anabolic mbụ kwadoro site na US Food and Drug Administration (FDA), na-amụba njupụta ọkpụkpụ n'ụzọ dị irè ma na-ebelata ihe ize ndụ mgbaji, iji ya ogologo oge na-ebu njedebe gụnyere mmụba ọkpụkpụ, hypercalcemia, na ihe ize ndụ dị ukwuu nke osteosarcoma.

Kedu usoro eji eme abaloparatide?

Mmekọrịta na Parathyroid Hormone Receptor 1 (PTH1R)

Nrụ ọrụ Nhọrọ nke Nnabata: Abaloparatide bụ agonist nhọrọ nke parathyroid hormone receptor 1 (PTH1R). PTH1R na-egosipụta nke ọma n'elu sel dị na anụ ahụ dị ka ọkpụkpụ na akụrụ, na-arụ ọrụ dị mkpa n'ịhazi metabolism ọkpụkpụ. Abaloparatide na-ejikọta kpọmkwem na PTH1R, na-amalite usoro nke ụzọ mgbaàmà intracellular iji mezie metabolism ọkpụkpụ. Mgbe ejikọtara ya, ọ na-arụ ọrụ adenylate cyclase, na-abawanye mmepụta intracellular cyclic AMP (cAMP) iji gbanwee ọrụ cellular na metabolism ^[1,2]..

Ọdịiche dị na njikọ ndị ọzọ: Parathyroid hormone (PTH) na protein parathyroid metụtara hormone (PTHrP) na-ejikọta na PTH1R. Ọ bụ ezie na PTH, PTHrP, na Abaloparatide niile sitere na PTH1R, ụzọ mgbama ala ha dị iche. PTH na PTHrP na-egosipụta ụdị mmekọ ahụ maka steeti R^G (GTPγS-sensitive) nke PTH1R. Teriparatid (TPTD, ntụgharị, 1-34 PTH) nwere njikọ dị elu okpukpu anọ maka steeti R^0 (GTPγS-enweghị mmetụta) karịa PTHrP, na-ebute akara CAMP ogologo oge nke TPTD kpatara. N'ụzọ dị iche, abaloparatide, nke sitere na PTHrP (1-34), emebere ya maka nkwụsi ike na-eme ka ọ dịkwuo elu ma merie nsogbu ndị dị ka mfu nke windo anabolic na hypercalcemia jikọtara ya na iji TPTD. N'ihi na ọnụ ọgụgụ dissociation nke PTHrP-PTH1R mgbagwoju dị ngwa ngwa karịa nke PTH-PTH1R mgbagwoju, mmetụta osteogenic nke PTHrP na-esonyere obere absorption na hypercalcemia karịa TPTD. Abaloparatide ketara uru nke a ^[1,2,3].

Iwu nke Ọkpụkpụ Metabolism

Nkwalite nke Osteogenesis: Abaloparatide na-akpali ọrụ osteoblast, na-amụba njikọ na ntinye nke ọkpụkpụ ọkpụkpụ iji kwalite ọkpụkpụ ọkpụkpụ. Osteoblasts na-emepụta ma na-ezobe ihe mejupụtara matriks ọkpụkpụ dị ka collagen na osteocalcin, nke na-eji nwayọọ nwayọọ mee ka ọkpụkpụ ọkpụkpụ dị ọhụrụ. Nnyocha na-egosi na n'ịgwọ ọrịa osteoporosis postmenopausal, abaloparatide na-abawanye ụba nke ịnweta ọkpụkpụ (BMD) na saịtị gụnyere mkpokọta hip, olu femoral, na spine lumbar. Site n'ịkwalite okwu nke mkpụrụ ndụ ihe nketa metụtara osteoblast, ọ na-emezi njikọ nke protein ndị dị mkpa dị ka osteocalcin na ụdị m collagen. Nke a na-akwalite mkpụkọ trabecular na ike cortical, na-eme ka ike na ịdị mma skeletal dịkwuo elu ma na-ebelata ihe ize ndụ mgbaji ^[1,2,3].

Mgbochi nke ọkpụkpụ ọkpụkpụ: Ọ bụ ezie na Abaloparatide na-arụ ọrụ dị ka onye na-ahụ maka anabolic, ọ na-egosipụtakwa ụfọdụ mmetụta mgbochi na ọkpụkpụ ọkpụkpụ. Ọ na-agbanwe ọdịiche na ọrụ nke osteoclasts-sel ndị na-ahụ maka resorption ọkpụkpụ nke na-agbaze mineral ọkpụkpụ na matrix organic site na ịhapụ ihe acidic na proteolytic enzymes. Abaloparatide nwere ike ibelata ọnụego resorption ọkpụkpụ site na ibelata ọdịiche nke sel precursor osteoclast n'ime osteoclasts tozuru oke ma ọ bụ na-ebelata ndụ nke osteoclasts tozuru oke. N'otu oge ahụ, ọ na-agbanwe akara n'etiti osteoblasts na osteoclasts, na-ejigide nha anya dị ike n'etiti nhazi ọkpụkpụ na resorption. Dịka ọmụmaatụ, ọ na-ebelata ọrụ osteoclast na ọrụ resorptive site na ibelata osteoblast nzuzo receptor activator nke κB ligand (RANKL). N'adịghị ka teriparatide, abaloparatide anaghị abawanye mmepụta RANKL nke ukwuu, si otú a na-egbochi mfu nke windo anabolic nke na-eme mgbe resorption gafere n'usoro n'ikpeazụ ^[1,2,3].

Mmetụta na Metabolism Cartilage (na ọmụmụ metụtara ọrịa ogbu na nkwonkwo)

Na-akwalite Synthesis Cartilage Matrix Synthesis: Nnyocha na ọrịa ogbu na nkwonkwo (OA) egosila na abaloparatide na-arụ ọrụ nchebe na cartilage. Chondrocytes articular na-egosipụta PTH1R, na Abaloparatide na-eme ka onye na-anabata ya rụọ ọrụ, na-akpali chondrocytes iji mepụta akụkụ nke matrix cartilage. Dịka ọmụmaatụ, ọmụmụ na-egosi Abaloparatide na-abawanye okwu lubricin (Prg4), protein dị mkpa nke matrix extracellular na cartilage nke dị oke mkpa maka idowe mmanu nkwonkwo na ibelata esemokwu. Ọ na-akwalitekwa njikọ nke ụdị II collagen, bụ isi akụkụ nke cartilage matrix, nke na-enyere aka ịnọgide na-enwe nguzozi nke cartilage na arụ ọrụ. Site n'ịbawanye njikọ nke akụrụngwa matrix cartilage ndị a, Abaloparatide na-enyere aka n'ịrụzi na ichekwa anụ ahụ mebiri emebi, na-ebelata ọganihu osteoarthritis ^[5]..

Na-egbochi hypertrophy chondrocyte na degeneration: Abaloparatide nwere ike igbochi usoro ọdịiche hypertrophic nke chondrocytes. N'oge osteoarthritis na-aga n'ihu, chondrocytes na-enweta ọdịiche hypertrophic, nke a na-eji ụda cell na-abawanye na nkwupụta dị elu nke ihe nrịbama hypertrophy dị ka ụdị X collagen (Col10). Usoro a na-eduga na mmebi nke matrix cartilage na cartilage degeneration. Nnyocha na-egosi na ọgwụgwọ Abaloparatide na-ebelata nkwalite okwu Col10 na anụ ahụ cartilage ma na-ebelata ọnụ ọgụgụ nke nnukwu hypertrophic-dị ka sel. Nke a na-egosi na ọ nwere ike belata ọdịiche hypertrophic chondrocyte, na-edobe phenotype chondrocyte nkịtị, si otú ahụ chebe cartilage na igbu oge ọganihu osteoarthritis ^[5].
