It remains a major public health concern as it causes almost 100% fatality and has no effective medication after the onset of the disease. However, this illness is preventable with the timely administration of effective post-exposure prophylaxis (PEP) consisting of the rabies vaccine and passive immune globulins (HRIG and ERIG). Recently, conventional PEP has been shown to have many limitations, resulting in little support for these expensive and heterologous globulins. Monoclonal antibody (mAb) production via recombinant technology in animal and human cell cultures, as well as a plant-based platform, was introduced to overcome the costly and high-tech constraints of former preparations. We used transient expression technology to produce two mAbs against the rabies virus in Nicotiana benthamiana and compared their viral neutralizing activity in vitro and in vivo. The expression levels of selective mAbs E559 and 62-71-3 in plants were estimated to be 17.3 mg\/kg and 28.6 mg\/kg in fresh weight, respectively. The plant-produced mAbs effectively neutralized the challenge virus CVS-11 strain in a cell-based RFFIT. In addition, the combination of these two mAbs in a cocktail protected hamsters from rabies virus infection more effectively than standard HRIG and ERIG. This study suggests that the plant-produced rabies antibody cocktail has promising potential as an alternative biological to polyclonal RIG in rabies PEP.<\/jats:p>","DOI":"10.3390\/vaccines11081377","type":"journal-article","created":{"date-parts":[[2023,8,17]],"date-time":"2023-08-17T10:49:00Z","timestamp":1692269340000},"page":"1377","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Efficiency Comparative Approach of Plant-Produced Monoclonal Antibodies against Rabies Virus Infection"],"prefix":"10.3390","volume":"11","author":[{"given":"Boonlert","family":"Lumlertdacha","sequence":"first","affiliation":[{"name":"Department of Animal Diagnosis and Investigation, Queen Saovabha Memorial Institute, Thai Red Cross Society, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bancha","family":"Mahong","sequence":"additional","affiliation":[{"name":"Department of Biological Products, The Government Pharmaceutical Organization, 75\/1 Rama VI Rd., Ratchet, Bangkok 10400, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaewta","family":"Rattanapisit","sequence":"additional","affiliation":[{"name":"Center of Excellence for Plant-Produced Pharmaceuticals, Pharmacognosy and Pharmaceutical Botany Department, Faculty of Pharmaceutical Sciences, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-6736-4132","authenticated-orcid":false,"given":"Christine Joy I.","family":"Bulaon","sequence":"additional","affiliation":[{"name":"Center of Excellence for Plant-Produced Pharmaceuticals, Pharmacognosy and Pharmaceutical Botany Department, Faculty of Pharmaceutical Sciences, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9480-2247","authenticated-orcid":false,"given":"Thiravat","family":"Hemachudha","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5958-7406","authenticated-orcid":false,"given":"Waranyoo","family":"Phoolcharoen","sequence":"additional","affiliation":[{"name":"Center of Excellence for Plant-Produced Pharmaceuticals, Pharmacognosy and Pharmaceutical Botany Department, Faculty of Pharmaceutical Sciences, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,17]]},"reference":[{"key":"ref_1","unstructured":"(2018).
