It is produced mainly by plasma cells in the spleen and lymph nodes. The functions of IgG include :1. Activate the classical complement pathway, mediate lysozyme and cytotoxicity; 2. 2. Mediate ADCC effect; Opsonphagocytosis; 3. 4. The SPA; Neutralize toxins and viruses...
of an anything-that-doesn’t-fit-in-the-first-four kingdom, which upset some people.And then there was the question of viruses.Viruses have some characteristics of life, but don't reproduce on their own or use energy.So we still don’t know what to do with them.The lumpers want to ...
And the extreme splitters say that viruses have nothing at all to do with living things and keep them out of my department. Recent research though has moved to see yet another direction. Nowadays when we want to determine the characteristics of something, we look at its biochemistry and its ...
Viruses have some characteristics of life but don’t reproduce on their own or use energy. So we still don’t know what to do with them. The lumpers want to keep viruses in the current system. Some of the splitters say to give them a separate kingdom. ...

Patients' characteristics were compared by causative agents' clinical picture and severity using Chi2 with a p < 0.05 significance. Overall, 317 patients were enrolled, 58.3% were 鈮 1 year of age, 61.5% were males. Of 229 (72.7%) of positively tested patients, viruses caused 92.1% ...
SARS-CoV-2 is thought to latch on to cells via spikes that exist on the surface of the virus. Thesespike proteinsare comprised of molecular motifs, stretches of amino acids that make a protein. These tiny molecular motifs may have what the scientists call "superantigen" characteristics, meanin...
