Txoj hauv kev no siv ntau tus neeg nqa khoom thiab cov phiaj xwm phiaj xwm txhawm rau txhim kho cov tshuaj sib xyaw hauv cov qog microenvironment, ua rau cov neeg mob tau txais txiaj ntsig zoo dua.

Kev nkag siab Targeted Drug Delivery rau Cancer

Dab tsi yog Targeted Drug Delivery rau Cancer?

Targeted tshuaj xa mus rau mob qog noj ntshav yog ib txoj hauv kev yooj yim ntawm kev muab tshuaj ncaj qha rau cov qog nqaij hlav cancer. Tsis zoo li cov tshuaj chemotherapy, uas cuam tshuam rau tag nrho lub cev, lub hom phiaj kev xa khoom tsom mus rau kev xa cov tshuaj tshwj xeeb rau cov qog nqaij hlav. Txoj kev no txo ​​qis kev puas tsuaj rau cov ntaub so ntswg noj qab haus huv thiab txo cov kev mob tshwm sim hnyav uas feem ntau cuam tshuam nrog kev kho mob qog noj ntshav.

Yog vim li cas Targeted Drug Delivery rau Cancer Tseem ceeb?

Lub hom phiaj tseem ceeb ntawm lub hom phiaj xa tshuaj rau mob qog noj ntshav yog txhawm rau txhim kho cov txiaj ntsig ntawm kev kho mob qog noj ntshav thaum txo cov tshuaj lom rau cov hlwb noj qab haus huv. Los ntawm kev xa cov tshuaj ncaj qha mus rau cov qog, qhov siab dua ntawm tus neeg sawv cev kho tuaj yeem ua tiav ntawm lub hom phiaj ntawm qhov chaw, txhim kho txoj hauv kev ntawm kev kho kom zoo. Qhov no kuj txo qis qhov cuam tshuam rau cov tshuaj, ua rau muaj kev phiv tsawg dua thiab tsis zoo rau tus neeg mob.

Txoj kev mus rau Targeted Drug Delivery rau Cancer

Passive Targeting

Passive targeting cia siab rau cov yam ntxwv ntawm cov qog nqaij hlav, xws li lawv cov vasculature leaky thiab impaired lymphatic kua, tso cai rau cov tshuaj mus rau hauv cov qog microenvironment. Nanoparticles uas tsim nyog qhov loj me thiab cov khoom saum npoo tuaj yeem siv cov yam ntxwv no rau cov qog nqaij hlav. Ib qho piv txwv yog liposomes uas yog cov vesicles kheej kheej uas muaj lipid bilayers.

Active Targeting

Lub hom phiaj tseem ceeb suav nrog kev hloov kho cov neeg nqa tshuaj nrog cov ligands tshwj xeeb uas khi rau cov receptors overexpressed ntawm cov qog nqaij hlav cancer. Qhov kev sib cuam tshuam no pab txhawb kev xaiv cov khoom siv tshuaj los ntawm cov qog nqaij hlav cancer. Cov ligands muaj xws li cov tshuaj tiv thaiv kab mob, peptides, thiab aptamers.

Stimuli-Responsive Targeting

Stimuli-responsive targeting siv cov stimuli sab hauv lossis sab nraud, xws li pH, qhov kub thiab txias, lossis lub teeb, ua rau cov tshuaj tso tawm ntawm qhov chaw qog. Txoj hauv kev no tso cai rau kev tswj xyuas meej txog kev xa tshuaj, ua kom muaj txiaj ntsig zoo tshaj plaws thaum txo qis cov txiaj ntsig tawm. pH-sensitive nanoparticles, piv txwv li, tso lawv cov tshuaj payload nyob rau hauv acidic ib puag ncig ntawm cov qog microenvironment.

Carriers siv nyob rau hauv Targeted Drug Delivery rau Cancer

Nanoparticles

Nanoparticles tau dav siv los ua cov khoom thauj hauv lub hom phiaj xa tshuaj rau mob qog noj ntshav vim lawv qhov me me, qhov loj ntawm qhov chaw, thiab versatility. Lawv tuaj yeem tsim los ntawm ntau yam ntaub ntawv, suav nrog lipids, polymers, thiab inorganic compounds. Nanoparticles tuaj yeem tsim kho los encapsulate tshuaj, tiv thaiv lawv los ntawm degradation, thiab pab txhawb lawv lub hom phiaj xa mus rau cov qog nqaij hlav cancer. Cov Shandong Baofa Cancer Research Institute siv ntau yam nanoparticles hauv lawv cov kev tshawb fawb txuas ntxiv mus rau kev kho mob qog noj ntshav tshiab.

Liposomes

Liposomes yog cov vesicles kheej kheej tsim los ntawm lipid bilayers. Lawv yog biocompatible, biodegradable, thiab muaj peev xwm encapsulate ob hydrophilic thiab hydrophobic tshuaj. Liposomes tuaj yeem hloov kho nrog lub hom phiaj ligands los txhim kho lawv cov kev xaiv rau cov qog nqaij hlav cancer.

Antibody-Drug Conjugates (ADCs)

ADCs yog tsim los ntawm monoclonal antibody txuas nrog cov tshuaj cytotoxic. Cov tshuaj tiv thaiv tau xaiv khi rau cov qog nqaij hlav cancer, xa cov tshuaj ncaj qha mus rau qhov chaw qog. Txoj hauv kev no ua ke nrog qhov tshwj xeeb ntawm cov tshuaj tiv thaiv kab mob nrog lub zog ntawm cov tshuaj cytotoxic.

Piv txwv ntawm Targeted Drug Delivery rau Cancer Hauv Kev Siv Tshuaj Kho Mob

Doxil? Liposomal Doxorubicin

Doxil? yog liposomal formulation ntawm doxorubicin, ib qho tshuaj anthracycline chemotherapy. Lub liposomal encapsulation ntawm doxorubicin prolongs nws lub sij hawm ncig thiab txhim kho nws tsub zuj zuj nyob rau hauv cov qog nrog leaky vasculature. Doxil? tau pom zoo rau kev kho mob ntawm zes qe menyuam, ntau yam myeloma, thiab Kaposi's sarcoma.

Kadcyla? (Trastuzumab Emtansine)

Kadcyla? yog ADC tsim los ntawm trastuzumab, monoclonal antibody uas tsom HER2, txuas rau emtansine, microtubule inhibitor. Kadcyla? tau pom zoo rau kev kho mob ntawm HER2-zoo metastatic mob cancer mis. Lub trastuzumab tivthaiv ntawm Kadcyla? khi rau HER2-zoo mob qog noj ntshav, xa cov emtansine ncaj qha mus rau qhov chaw qog.

Cov kev sib tw thiab cov kev taw qhia yav tom ntej

Overcoming Biological Barriers

Ib qho kev sib tw loj hauv lub hom phiaj xa tshuaj rau mob qog noj ntshav yog overcoming biological barriers, xws li ntshav-hlwb barrier thiab cov qog microenvironment. Cov tswv yim los kov yeej cov teeb meem no suav nrog kev siv cov nanoparticles me me, hloov kho lawv cov khoom nto, thiab siv lub hom phiaj stimuli teb.

Txhim kho lub hom phiaj tshwj xeeb

Kev txhim kho qhov tshwj xeeb ntawm cov phiaj xwm xa tshuaj yog qhov tseem ceeb kom txo qis cov txiaj ntsig tawm ntawm lub hom phiaj thiab txhim kho cov txiaj ntsig kho mob. Qhov no tuaj yeem ua tiav los ntawm kev tsim cov ligands xaiv ntau dua, ua kom zoo rau kev tsim cov neeg nqa tshuaj, thiab siv cov kev kho mob sib xyaw ua ke.

Tshuaj kho tus kheej

Cov tshuaj kho tus kheej txoj hauv kev tau cog lus zoo rau kev txhim kho cov txiaj ntsig ntawm lub hom phiaj xa tshuaj rau mob qog noj ntshav. Los ntawm kev kho cov tswv yim kho mob rau tus kheej tus yam ntxwv ntawm txhua tus neeg mob thiab lawv cov qog, nws tuaj yeem ua kom zoo dua kev xa tshuaj thiab txhim kho cov txiaj ntsig kev kho mob. Qhov no yuav suav nrog kev txheeb xyuas cov caj ces ntawm cov qog los txheeb xyuas cov hom phiaj tshwj xeeb rau kev xa tshuaj.
