    Passive immunity, which is the body's ability to passively accept antibodies, sensitizing lymphocytes or their products, is considered an effective means of treating neo-coronary pneumonia.it needs to be given to patients with a formulation that neutralizes the virus - either a serum for a newly coronavirus-infected person or a purified antibody., however, although some antibodies have been found to neutralise the virus by blocking the combination of the virus's stingprotein with ACE2, unfortunately, many do not cross-react with the new crown virus.human-derived antibodies, like most mammalian antibodies, have heavy and light chains, while camels such as large alpacas have a variant of an antibody with only a single heavy chain, also known as nano-antibodies.nanoantibodies are small and stable and easy to prepare, so they are often used as an alternative to traditional antibodies for diagnostic and imaging.are currently developing nanoantibodies that could be used as research tools and potential therapeutic drugs for the new coronavirus., James Neismith, a scientist at the Rosalynn Franklin Institute in the United Kingdom, and colleagues reported on two closely related nanoantibodies (H11-H4 and H11-D4) that block the combination of new coronavirus stings and ACE2 in cell culture.a protein region targeted by these nanoantibodies is closely adjacent to the ACE2 binding region and has a small overlap.both nano-antibodies show edimen's ability to neutralise the new coronavirus, where H11-H4 has a particularly high price, and the use of human-derived antibodies can also enhance neutrality and ability.the team believes that these nano-antibodies can be used alone or in combination with other antibodies to help patients with severe pneumonia achieve passive immunity.because camel-derived antibodies are highly conservative to human-derived antibodies, they may only produce a lower immune response in the human body, but they can be used to develop sophisticated human-derived strategies..
