Sentences with phrase «at invading cells»

Furthermore, laboratory experiments demonstrated that strains with the rare amino acid combination 519I / 549H in the CDV - H - protein were significantly better at invading cells with lion or domestic cat receptors than cells with domestic dog receptors.

The laboratory experiments also showed that the amino acid combination in the CDV - H protein typically found in domestic dog strains (519R / 549Y) was particularly good at invading cells with domestic dog receptors but far less efficient at entering cells with non-canid receptors, effectively making domestic dog strains less able to infect lions and spotted hyenas if they are exposed to them.
