Surface molecules in the greenhouse strike the air molecules touching them, setting them in motion. (drtimball.com)
These markers include a broad spectrum of surface molecules such as CD44 (15675 -1-AP), CD24 (18330 -1-AP), CD1333 (18470 -1-AP, Figure 2), or LC3B (18725 -1-AP, Figure 3). (ptglab.com)
Equally important, they developed surface molecules called integrins that are only produced when CD4 cells are destined for mucosal surfaces, such as those in the vagina. (newscientist.com)
