Abstract

We have established IL-3-dependent 32D myeloid progenitor cells stably expressing the human IL-2 receptor beta chain (IL-2R beta). Whereas parental 32D cells proliferated only in response to IL-3, the transduced cells also proliferated in response to IL-2. Transduced cells expressed high- and intermediate-affinity IL-2Rs, resulting from expression of human IL-2R beta and murine IL-2R alpha chain (IL-2R alpha). IL-2 induced phenotypic changes not induced by IL-3, including the upregulated expression of endogenous murine IL-2R alpha and IL-2R beta and an increase in cell size. Therefore, the transduced IL-2R beta was not merely coupling with the IL-3 signaling pathway. IL-3 augmented several IL-2-induced responses including the up-regulation of IL-2R alpha. Both IL-2- and IL-3-induced proliferation and IL-2 induced IL-2R alpha expression were inhibited by the tyrosine kinase inhibitor herbimycin A. Thus, both IL-2- and IL-3-mediated effects required tyrosine kinase activity. The identity of the tyrosine kinase(s) mediating the IL-2 signals in these cells is not known but cannot be p56lck, a tyrosine kinase found in T cells, since 32D-IL-2R beta cells do not express p56lck.

Interleukin (IL)-2 and IL-3 induce distinct but overlapping responses in murine IL-3-dependent 32D cells transduced with human IL-2 receptor beta chain: involvement of tyrosine kinase(s) other than p56lck.

Abstract

Capsular types of pneumococci from normally sterile body sites of 1,622 patients in Brazil were analyzed. Of 1,477 isolates from cerebrospinal fluid, 76.1% were of types represented in the currently available pneumococcal vaccine. The importance of age, time, and place in determining the optimal formulation of pneumococcal vaccine is considered.

Abstract

Single-stranded DNA was complexed to the single-strand binding protein (SSB) of Escherichia coli in a mass ratio of 30:1. The protein moiety of this complex can be labelled by a number of methods of which we have chosen radio-iodination and biotinylation as examples. The SSB-M13 DNA complexes, labelled to high specific activities, were used as probes in hybridization experiments in which 1.6 X 10(-18) moles of immobilized target DNA were detected. The stability of the hybrids was not severely decreased by the binding of SSB. Analysis of hybrids by electron microscopy showed that complexing of DNA with SSB could be used to allow its subsequent identification in the hybrids.
