The strength of synaptic transmission is highly variable between different synapses. The present study examined some factors that may contribute to this variation in the strength of neurotransmission in sympathetic varicosities of the mouse vas deferens. Transmitter release was measured using a focal macropatch electrode placed over pairs of visualised varicosities. By regulating the calcium concentration of the solutions inside the recording electrode and in the bath independently of each other, transmitter release was restricted to one or two surface varicosities at each recording site. Using this technique, transmitter release probability was shown to be highly variable, even between adjacent varicosities on single axon branches. Very little variation was observed in the calcium influx following single impulse nerve stimulation between adjacent Oregon Green BAPTA-1 loaded varicosities. However, the staining intensities of three vesicular proteins, SV2, synaptophysin, and synaptotagmin 1, showed considerable variation between adjacent varicosities on single axon branches. This variation in staining intensity may be partly explained by variation in the density of synaptic vesicles. However, double staining experiments using two vesicular antigens showed some varicosities staining for one vesicular antigen, but not for the second, suggesting that the expression of these release machinery proteins is regulated locally within the varicosities. The results of the present study strengthen suggestions that synaptic strength is at least in part, regulated by variation in the expression of vesicular proteins. (C) 2004 Wiley-Liss, Inc.

To our knowledge, there has been no report of spontaneous regression in a non-immunocompromised adult with classical Hodgkin's lymphoma (HL) in the absence of chemotherapy. We describe spontaneous regression and subsequent relapse of Epstein - Barr virus (EBV)-positive HL in an otherwise healthy male adult. The clinical course was associated with an increase in regulatory T-cell markers within the peripheral blood and diseased lymph node at the time of relapse and with a concomitant reduction in cellular immunity against relevant EBV latent membrane protein tumor-associated antigens. Our findings are in keeping with previous observations that implicate impaired cellular immunity in the immunopathogenesis of EBV-positive HL.
