Targeted Drug Delivery for Cancer: Ib Daim Ntawv Qhia Tag Nrho 

Targeted tshuaj xa mus rau mob qog noj ntshav tsom rau kev xa cov tshuaj kho mob tshwj xeeb rau cov qog nqaij hlav cancer, txo qis kev puas tsuaj rau cov ntaub so ntswg noj qab haus huv. Txoj hauv kev no siv ntau lub tswv yim, suav nrog nanoparticles, tshuaj tiv thaiv kab mob, thiab cell-peptides, txhawm rau txhim kho kev siv tshuaj thiab txo cov kev mob tshwm sim, muab kev kho mob qog noj ntshav ntau dua thiab tus kheej.

Kev nkag siab Targeted Drug Delivery rau Cancer

Kev kho mob qog noj ntshav tau hloov zuj zus mus, nrog lub hom phiaj xa tshuaj rau mob qog noj ntshav tawm los ua ib qho kev cog lus zoo. Txoj hauv kev no yog txhawm rau xaiv cov tshuaj xa mus rau cov qog nqaij hlav cancer, ua kom muaj txiaj ntsig zoo tshaj plaws thaum txo kev puas tsuaj rau cov ntaub so ntswg noj qab haus huv. Tsis zoo li cov kws kho mob ib txwm siv, uas faib cov tshuaj thoob plaws hauv lub cev, lub hom phiaj kev xa khoom siv ntau lub tswv yim txhawm rau tsom mus rau cov qog nqaij hlav cancer.

Vim li cas Targeted Drug Delivery rau Cancer Teeb meem

Cov tshuaj chemotherapy feem ntau ua rau muaj kev phiv loj heev vim nws cuam tshuam rau cov qog nqaij hlav cancer thiab noj qab nyob zoo. Targeted tshuaj xa mus rau mob qog noj ntshav muab kev daws teeb meem los ntawm kev xa cov tshuaj ncaj qha mus rau qhov chaw qog. Qhov no txo ​​cov tshuaj toxicity, txhim kho cov tshuaj ua tau zoo, thiab muaj peev xwm txhim kho tus neeg mob lub neej zoo.

Tswv yim rau Targeted Drug Delivery rau Cancer

Ob peb lub tswv yim tshiab yog siv rau hauv lub hom phiaj xa tshuaj rau mob qog noj ntshav, txhua tus nrog nws tus kheej zoo thiab kev txwv.

Nanoparticles

Nanoparticles yog cov khoom me me (1-100 nm) tsim los encapsulate thiab xa cov tshuaj mus rau cov qog nqaij hlav cancer. Lawv tuaj yeem tsim kho kom pom cov receptors tshwj xeeb ntawm cov qog nqaij hlav cancer, xws li EGFR lossis HER2. Liposomes, polymeric nanoparticles, thiab inorganic nanoparticles feem ntau yog siv. Kev txhim kho permeability thiab khaws cia (EPR) cov nyhuv tso cai rau cov nanoparticles kom dhau los ua cov ntaub so ntswg vim qhov xau vasculature.

Piv txwv: Doxil, liposomal doxorubicin, yog cov khoom lag luam uas muaj nanoparticle-based tshuaj siv los kho mob qog noj ntshav ntawm zes qe menyuam thiab ntau yam myeloma.

Antibody-Drug Conjugates (ADCs)

ADCs muaj cov tshuaj tiv thaiv monoclonal txuas nrog cov tshuaj cytotoxic. Cov tshuaj tiv thaiv tshwj xeeb khi rau lub hom phiaj antigen ntawm cov qog nqaij hlav qog noj ntshav, ua rau muaj kev cuam tshuam ntawm ADC thiab tom qab tso tawm cov tshuaj hauv lub cell.

Piv txwv: Adcetris (brentuximab vedotin) tsom rau CD30, ib qho protein uas pom ntawm qee cov qog ntshav qog ntshav, xa cov microtubule- cuam tshuam tus neeg sawv cev.

Cell-Penetrating Peptides (CPPs)

CPPs yog luv luv amino acid sequences uas pab txhawb kev nkag ntawm cov tshuaj los yog nanoparticles rau hauv hlwb. Lawv tuaj yeem raug txuas mus rau cov tshuaj kho mob lossis nanoparticles los txhim kho lawv cov cellular uptake.

Receptor-Mediated Endocytosis

Cov tswv yim no suav nrog kev tsom mus rau receptors uas tau nthuav tawm ntau dhau ntawm cov qog nqaij hlav cancer. Ligands lossis cov tshuaj tiv thaiv kab mob uas khi rau cov receptors no yog siv los xa cov tshuaj los yog nanoparticles ntawm endocytosis.

Shandong Baofa Cancer Research Institute lub luag haujlwm

Lub koom haum Shandong Baofa Cancer Research Institute tau koom tes nrog kev tshawb fawb thiab tsim cov tshiab lub hom phiaj xa tshuaj rau mob qog noj ntshav tshuab. Lawv cov kev tshawb fawb tsom mus rau tus kheej txoj hauv kev uas xav txog qhov tshwj xeeb genetic thiab molecular profiles ntawm ib tus neeg mob, txhawm rau txhim kho cov txiaj ntsig kev kho mob thiab txo qis cov kev mob tshwm sim.

Shandong Baofa Cancer Research Institute ua haujlwm nrog cov tsev kho mob zoo li Shandong Baofa Cancer Hospital (https://baofahospital.com) los ua cov kev sim tshuaj ntsuam xyuas thiab txhais cov kev tshawb fawb tshawb pom rau hauv cov ntawv thov.

Qhov zoo ntawm Targeted Drug Delivery rau Cancer

Targeted tshuaj xa mus rau mob qog noj ntshav muaj ntau qhov zoo ntawm cov tshuaj chemotherapy:

• Txo toxicity: Los ntawm kev tsom mus rau cov qog nqaij hlav cancer tshwj xeeb, qhov cuam tshuam ntawm cov ntaub so ntswg noj qab haus huv rau cov tshuaj lom yog txo qis, ua rau muaj kev phiv tsawg.
• Txhim kho kev ua tau zoo: Cov tshuaj ntau dua tuaj yeem xa ncaj qha mus rau qhov chaw qog, uas tuaj yeem ua rau muaj txiaj ntsig zoo.
