Abstract: The present invention provides methods and compositions comprising a heterodimeric antibody comprising a first monomer comprising a first variant heavy chain constant region and an anti-CD4 binding moiety. The heterodimeric antibody also comprises a second monomer comprising: a second variant heavy chain constant region and an anti-CD25 binding moiety. In some cases, the pIs of the first and second variant heavy chain constant regions are at least 0.5 logs apart.
