    Notes: Abstract— Frozen and unfrozen bovine brains were used to determine the extent of in situ degradation of myelin basic protein. The following three parameters were investigated. (1) The time interval between death and sampling of the tissue, (2) the effective temperature of the tissue during this interval, and (3) the effect of freezing and thawing on the subsequent autolysis of myelin basic protein. Polyacrylamide gel electrophoresis was carried out on unfrozen white matter solubilized with phenol-formic acid–water. The resulting electrophoretic pattern showed no qualitative changes in the myelin basic protein after tissue incubation at 4° or 23°C for up to 24 h. When myelin basic protein was extracted, purified and quantitated, there was no apparent decrease within 24 h of incubation at 23°C. However, if the tissue was frozen and thawed prior to incubation, there was a rapid disappearance of myelin basic protein such that only 10% remained after 24 h of incubation. Basic protein extracted from frozen or unfrozen tissue that had undergone autolysis for up to 24 h was found to be encephalitogenic in guinea pigs. Electron microscopy of frozen and thawed material showed separation and fraying of myelin lamellae. It is postulated that the above morphological changes probably render the basic protein readily accessible to proteolytic enzymes.

    Notes: Abstract: Specific immunotherapy and other immunomodulatory strategies have long been a stronghold in the management of allergic diseases. In particular, “immunodeviation-therapy” or “vaccination for allergies”, i.e. the redirection of Th2-type immune responses towards a Th1-response pattern, has become an ever more popular concept. The present feature of CONTROVERSIES complements our previous discussion of atopy (Röcken et al., Exp Dermatol 7: 97–104, 1998), and is dedicated to a critical analysis of the general problems and limitations one faces with the main immunomodulatory strategies traditionally considered in this context. We also explore alternative approaches that appear promising in order to achieve both a more effective and/or a more specific immunotherapy of allergic diseases. Given that the mast cell remains a key protagonist in the pathogenesis of allergic diseases finally, this feature examines how innovative, more selectively mast cell-targeted strategies may be developed for the management of allergic diseases.

    Direct characterization of human T cells in pemphigus vulgaris reveals elevated autoantigen-specific Th2 activity in association with active disease (2005)

    Notes: Pemphigus vulgaris (PV) is a blistering skin disorder mediated by autoantibodies targeting the epidermal adhesion molecule desmoglein 3 (Dsg3). As Th2-associated cytokines are necessary for directing antibody production, it is hypothesized that Dsg3-specific Th2 activity is associated with active disease. We used cell-surface-matrix technology in combination with flow cytometry to characterize the Dsg3-reactive T-cell population using peripheral blood mononucleocytes sampled from PV patients stratified by active (n = 9) or remittent disease (n = 6), and healthy human leucocyte antigen-matched controls (n = 5). We evaluated interferon-γ-producing CD4+ cells (Th1) and interleukin (IL)-10- or IL-4-producing CD4+ cells (Th2). The mean frequency of Th2 CD4+ T cells was significantly elevated for five of nine PV patients with active disease. No significant Th2 responses were detected for patients with remittent disease or controls. There was a significant association of Th2 activity with active disease compared with remittent and control groups (P = 0.026 and P =0.012, respectively), and Th2 activity was significantly correlated with anti-Dsg3 IgG titre (P = 0.044). One patient with remittent disease converted from a Th2-negative to a Th2-positive response with the initiation of disease activity. An antigen-specific CD4− lymphocyte response was detected in five PV patients (36%), and was shown to correlate closely with the CD8+ population. These results are consistent with the hypothesis that Th2 response directs autoantibody production and is therefore associated with disease activity in PV.
