Advances in the production of antibodies in plants
Angelis, Karel ; Šmídková, Markéta
Plants are the oldest biotechnological production system and as eukaryots have advantage over bacteria to modify expressed proteins. Laboratory model plants like tobacco along with crop plants with established logistics for harvest and storage like potatoes or rice are used for production of desired proteins. Current trend is to replace soil grown plants with liquid cultures of plant cells grown under controlled conditions. In this respect the moss Physcomitrella patens besides ability to grow in liquid culture enables due to efficient homologous recombination to modify posttranslational glycosylation to correspond human. For heterologous expression in plants, recombinant, single-chain molecules composed of only variable VL and VH regions of the original antibody forming binding pocket are constructed and expressed. Recombinant scFv antibodies are then used as a part of therapeutic or diagnostic drugs in oncology.

Polymerní konjugát doxorubicinu na bázi HPMA, působící ve shodě s protinádorovou imunitou nositele
Šírová, Milada ; Rossmann, Pavel ; Mrkvan, Tomáš ; Strohalm, Jiří ; Šubr, Vladimír ; Plocová, Daniela ; Ulbrich, Karel ; Říhová, Blanka
Polymeric conjugate Dox-HPMA-HuIg directly targets the tumour due to the EPR effect, it is not detrimental towards the immune system of the host, and acts in concert with the anti-tumour immune responses

Kopolymery na bázi HPMA s pH-řízeným uvolňováním doxorubicinu v protinádorové terapii umožňují imunitnímu systému rozpoznat nádor

Therapy with HPMA-based conjugates triggers effective anti-tumour immunity early during the course of the treatment. Activated immune system, in addition to direct cytotoxic effect the drug, is responsible for the eradication of established tumour

Protinádorová účinnost konjugátu na bázi N-(2-hydroxypropyl)metakrylamidu, obsahujícího doxorubicin a normální lidský imunoglobulin
Šírová, Milada ; Strohalm, Jiří ; Rossmann, Pavel ; Mrkvan, Tomáš ; Šubr, Vladimír ; Plocová, Daniela ; Ulbrich, Karel ; Říhová, Blanka
Polymeric conjugate based on HPMA containing cytotoxic drug (doxorubicin) and human “non-specific” immunoglobulin has a significant anti-tumour effect and does not impair immune functions of the host. C57BL/6 mice with EL-4 lymphoma, when completely cured with the conjugate, were protected against the same tumour due to a specific anti-tumour immune reaction
