Sodium Is Not Required for Chloride Efflux via Chloride/Bicarbonate Exchanger from Rat Thymic Lymphocytes

Figure 2

Chloride efflux from thymocytes (treated either with H2DIDS ( ) or with NMDG ( )) into chloride-free, bicarbonate-containing, and either sodium-containing or sodium-free medium. The smooth curves correspond to model (2) (noncontrollable chloride efflux) or model (4) (taking into account the contribution of the exchanger) with the parameter values presented in Table 2. The controls were Na isethionate (a) and D-mannitol (b). The data (zigzagged lines) are representative of (a) and experiments (b).
