These protein structures bind and neutralize a wide variety of pathogens, and are an important part of the immune response generated following vaccination against SARS-CoV-2. They also represent a potential treatment for COVID-19 patients, whereby lab-produced antibodies can be administered to such patients to help them to combat the virus. However, producing antibodies is costly and complex, and it is not currently possible to create enough supplies to treat everyone who needs them.<\/p>\n<p>In contrast, nanobodies, which are more easily manufactured, could be a viable alternative. This latest creation is shaping up to be a promising drug candidate for COVID-19. \u201cFor the first time, they combine extreme stability and outstanding efficacy against the virus and its Alpha, Beta, Gamma, and Delta mutants,\u201d said Dirk G\u00f6rlich, a researcher involved in the study, in a press release.<!-- ASYNC UAT M - 300x250(t,r) - --><\/p>\n<p><!-- END ASYNC UAT M - 300x250(t,r) --><\/p>\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-large\"><img decoding=\"async\" data-lazy-type=\"image\" src=\"https:\/\/www.medgadget.com\/wp-content\/uploads\/2021\/08\/alpaca-inhibitors-of-covid-1.jpg\" alt=\"\" class=\"lazy lazy-hidden wp-image-1517266\" srcset=\"https:\/\/www.medgadget.com\/wp-content\/uploads\/2021\/08\/alpaca-inhibitors-of-covid-1.jpg 466w, https:\/\/www.medgadget.com\/wp-content\/uploads\/2021\/08\/alpaca-inhibitors-of-covid-1-300x169.jpg 300w\" data-lazy-sizes=\"(max-width: 466px) 100vw, 466px\"\/><noscript><img decoding=\"async\" src=\"https:\/\/www.medgadget.com\/wp-content\/uploads\/2021\/08\/alpaca-inhibitors-of-covid-1.jpg\" alt=\"\" class=\"wp-image-1517266\" srcset=\"https:\/\/www.medgadget.com\/wp-content\/uploads\/2021\/08\/alpaca-inhibitors-of-covid-1.jpg 466w, https:\/\/www.medgadget.com\/wp-content\/uploads\/2021\/08\/alpaca-inhibitors-of-covid-1-300x169.jpg 300w\" sizes=\"(max-width: 466px) 100vw, 466px\"\/><\/noscript><figcaption>The three alpaca mares\u00a0Britta, Xenia, and Nora provided the starting point for the COVID-19 nanobodies. <br \/>Credit: Carmen Rotte \/ Max Planck Institute for Biophysical Chemistry<\/figcaption><\/figure>\n<\/div>\n<p>The Max Planck team use Alpacas to produce the nanobodies by immunizing them against the viral spike protein and then isolating the nanobodies from the blood before further purification and testing. \u201cOur nanobodies originate from alpacas and are smaller and simpler than conventional antibodies,\u201d said G\u00f6rlich. \u201cThe overall burden on our animals is very low, comparable to vaccination and blood testing in humans.\u201d<\/p>\n<p>Strikingly, the new nanobodies have a very high heat tolerance, something that is important for their stability in the body and which can be a sticking point for many biological treatments. \u201cOur nanobodies can withstand temperatures of up to 95 \u00b0C without losing their function or forming aggregates,\u201d said Matthias Dobbelstein, another researcher working on the project. \u201cFor one thing, this tells us that they might remain active in the body long enough to be effective.
