Both during phylogeny and ontogeny the thymus appears as a nodal point between the two major systems of cell-to-cell signaling, the neuroendocrine and immune systems. This review presents the experimental observations which support a dual role in T cell selection played by the thymic repertoire of neuroendocrine polypeptide precursors. Through the mode of cryptocrine intercellular signaling thymic neuroendocrine-related precursors synthesized in thymic epithelial cells have been shown to influence the early steps in T cell differentiation. In addition, thymic neuroendocrine-related polypeptides are a source of self-antigens which are presented by the major histocompatibility system of the thymic epithelium. Preliminary data also suggest that the intrathymic T cell education to neuroendocrine self-antigens is not strictly superimposible to the antigen presentation by dedicated presenting cells. Insulin-like growth factor-II (IGF-II) was identified as one dominant member of the insulin family expressed by thymic epithelial and nurse cells. The intrathymic presentation of IGF-II or IGF-II derived self-antigens is under current investigation. If further confirmed, the central tolerogenic properties of IGF-II could be considered in the elaboration of a strategy for an efficient and safe prevention of insulin-dependent diabetes. [less ▲]

Phosphates of compositions (Na1-xLix)(1.5)Mn1.5Fe1.5(PO4)(3) were synthesized by solid state reactions in air, and pure alluaudite-type compounds were obtained for x = 0.00, 0.25, and 0.50. Rietveld refinements of X-ray powder diffraction data indicate the occurrence of Mn2+ in the M(1) site, and of Fe3+ and Mn2+ in the M(2) site. For x = 0.25 and 0.50, A(1) is occupied by Li+ and Na+, whereas A(2)' is occupied by Na+ and vacancies. A careful examination of the number of electrons occurring in the A sites of the alluaudite-type compounds (Na1-xLix)MnFe2(PO4)(3) and (Na1-xLix) CdIn2(PO4)(3) confirms that lithium occupies only the A(1) crystallographic site of the alluaudite structure.

Several compounds of the (Na1-xLix)CdIn2(PO4)(3) solid solution were synthesized by a solid-state reaction in air, and pure alluaudite-like compounds were obtained for x = 0.00, 0.25, and 0.50. X-ray Rietveld refinements indicate the occurrence of Cd2+ in the M(1) site, and of In3+ in the M(2) site of the alluaudite structure. This non-disordered cationic distribution is confirmed by the sharpness of the infrared absorption bands. The distribution of Na+ and Li+ on the A(1) and A(2)' crystallographic sites cannot be accurately assessed by the Rietvled method, probably because the electronic densities involved in the Na+ --> Li+ substitution are very small. A comparison with the synthetic alluaudite-like compounds, (Na1-xLix)MnFe2(PO4)(3), indicates the influence of the cations occupying the M(1) and M(2) sites on the coordination polyhedra morphologies of the A(1) and A(2)' crystallographic sites.
