cell-pathogen interactions. They play critical roles for the immune system in leukocyte …

The regulation of integrin function by divalent cations

K Zhang, JF Chen - Cell adhesion & migration, 2012 - Taylor & Francis
Integrins are a family of α/β heterodimeric adhesion metalloprotein receptors and their
functions are highly dependent on and regulated by different divalent cations. Recently …
