  1. MP subsets present in BAL. MP subsets are defined by the flow cytometry gates in Fig. 1b. Expression of defining antigens is indicated as “++” bright expression, “+” positive expression, “+/−” low-level expression or “−” no expression. Where no symbol is given, expression was not measured on that subset. Frequencies of each MP subset in whole blood, SS BAL and LPS BAL are given. In standard type, frequencies are given as a percentage of total leukocytes (defined as CD45+ cells). In italic type, frequencies are given as a percentage of MPs (defined as CD45+SSClo, CD3,19,20,56 HLA-DR+ cells)
