Receptors for thymosin fraction V on rat thymic lymphocytes

Summary Binding by rat thymus lymphocytes of thymosin V, labeled with colloidal gold, was studied. Under the experimental conditions employed at least 2.8% cells exhibited thymosin binding sites.This article originally appeared in Experientia 38 (5) 1982, p. 618 but was accompanied by imporperfigures. Supported by Polish Academy of SciencesThe authors thank Dr A.L. Goldstein for the gift of thymosin. Also are grateful to Dr J. Jaroszewski for helpful discussion.     

Degenerative atrophy of central terminals of primary sensory neurons induced by blockade of axoplasmic transport in peripheral nerves

Summary Perineural colchicine- or vinblastine-treatment results in disappearance of non-lysosomal acid phosphatase activity, characterizing axon terminals in the Rolando substance of the normal spinal cord. Ultrastructural alterations are identical with those seen in the course of degenerative atrophy.Supported by research grant No. 4-01-0303-01-1 from the Hungarian Ministry of Health.     

Structure of an antibody combining site by magnetic resonance.

The structure of the combining site of the DNP binding IgA mouse myeloma protein MOPC 315 has been determined by a combination of high resolution nuclear magnetic resonance, electron spin resonance, model building and chemical modifications. This approach yields that general dimensions of the site, its polarity and asymmetry features, the assignment of the DNP-contact residues and their three-dimensional coordinates.
