Schallenberg S, Tsai PY, Riewaldt J, Kretschmer K. Identification of an immediate Foxp3 − precursor population to Foxp3 + regulatory T cells in
peripheral lymphoid organs of non-manipulated mice.
His group defined a functional niche for B cells (around sinusoids in the bone marrow), identified the first two mutants that abrogate marginal zone B lymphocyte development, developed the concept of a follicular versus marginal zone B
lymphoid cell - fate decision, and discovered two new defined stages of
peripheral B cell development, the marginal zone precursor (MZP) B cell, and the Follicular type II B cell.
