Abstract
Candida albicans is both a commensal and a pathogen at the oral mucosa. Although an intricate network of host defense mechanisms are expected for protection against oropharyngeal candidiasis, anti-Candida host defense mechanisms at the oral mucosa are poorly understood. Our laboratory recently showed that primary epithelial cells from human oral mucosa, as well as an oral epithelial cell line, inhibit the growth of blastoconidia and/or hyphal phases of several Candida species in vitro with a requirement for cell contact and with no demonstrable role for soluble factors. In the present study, we show that oral epithelial cell-mediated anti-Candida activity is resistant to gamma-irradiation and is not mediated by phagocytosis, nitric oxide, hydrogen peroxide, and superoxide oxidative inhibitory pathways or by nonoxidative components such as soluble defensin and calprotectin peptides. In contrast, epithelial cell-mediated anti-Candida activity was sensitive to heat, paraformaldehyde fixation, and detergents, but these treatments were accompanied by a significant loss in epithelial cell viability. Treatments that removed existing membrane protein or lipid moieties in the presence or absence of protein synthesis inhibitors had no effect on epithelial cell inhibitory activity. In contrast, the epithelial cell-mediated anti-Candida activity was abrogated after treatment of the epithelial cells with periodic acid, suggesting a role for carbohydrates. Adherence of C. albicans to oral epithelial cells was unaffected, indicating that the carbohydrate moiety is exclusively associated with the growth inhibition activity. Subsequent studies that evaluated specific membrane carbohydrate moieties, however, showed no role for sulfated polysaccharides, sialic acid residues, or glucose- and mannose-containing carbohydrates. These results suggest that oral epithelial cell-mediated anti-Candida activity occurs exclusively with viable epithelial cells through contact with C. albicans by an as-yet-undefined carbohydrate moiety.

Abstract
The general responsiveness of human melanoma to immunotherapy has been well established, but active immunotherapy of melanoma has been hampered by insufficient information on the immunogenicity of melanoma-associated Ags in patients. In this study, we isolated a recombinant phage-Fab clone (A10-5) from a phage-Fab library derived from the B cells of a melanoma patient in remission after immunotherapy. Purified A10-5 Fab bound at high levels to cultured melanoma cell lines and to tissue sections of metastatic and vertical growth phase primary melanoma, but not to radial growth phase primary melanoma, nevi, or normal skin. A10-5 Fab bound to both the surface and the cytoplasm of cultured melanoma cells, but only to the cytoplasm of cultured fibroblasts. Western blot analysis revealed A10-5 Fab reactivity with a 33- and a 23-kDa glycoprotein under nonreducing conditions, and with a 23-kDa protein only under reducing conditions. A cDNA with an open reading frame predicted to encode a 23-kDa protein was cloned by screening a melanoma cell cDNA library with A10-5 Fab. This protein (p23) is the human homologue of the murine tumor transplantation Ag P198 that interacts with the cytoplasmic domain of ErbB-3 expressed by melanoma cells. Thus, the Ab phage display method has identified a novel, stage-specific melanoma-associated Ag that may have therapeutic and diagnostic value.

Abstract
Oropharyngeal candidiasis (OPC) caused by Candida albicans is a significant problem in human immunodeficiency virus (HIV)-infected persons. Recognizing the paucity of information on innate and/or adaptive mucosal host defenses against C. albicans, we recently reported that human and nonhuman primate and mouse vaginal epithelial cells inhibit the growth of C. albicans in vitro. In the present study, oral epithelial cells collected from saliva of healthy volunteers and a purified oral epithelial cell line were found to inhibit blastoconidia and/or hyphal growth of several Candida species. Cell contact was a strict requirement for the epithelial cell anti-Candida activity; neither saliva nor culture supernatants alone inhibited Candida growth, and addition of saliva to the coculture did not modulate the epithelial cell activity. Finally, epithelial cell anti-Candida activity was significantly lower in HIV-infected persons with OPC. Together, these results suggest that oral epithelial cells may play a role in innate resistance against OPC.

Abstract
Mucosal candidiasis is common in human immunodeficiency virus (HIV) infection. Susceptibility to such infections may be attributed to reduced host defense mechanisms and/or virulence of the organism. In the present study, we compared the virulence of mucosal Candida albicans isolates from HIV-infected people, with and without fluconazole-refractory infection, in established murine models of systemic and vaginal candidiasis. Compared with the mortality rate ( approximately 70%) after intravenous challenge with 2 virulent reference isolates, challenge with most clinical isolates (66%-77%) resulted in prolonged survival. In contrast, fungal burden induced by intravaginal challenge of nearly all (97%) isolates was similar to that of the virulent controls. There were no differences in in vitro growth rates for any of the isolates, and there was no association between reduced mortality and clinical failure to fluconazole, in vitro antifungal susceptibility, site of infection, or other host factors. These results suggest that virulence of C. albicans is tissue specific and is not a factor in the development of fluconazole-refractory infections in advanced HIV disease.

Abstract
A block method for the solid phase synthesis (SPPS) of serine phosphopeptides has been developed using a combination of Fmoc and Alloc strategies. Alloc-Ser[PO(OCH2CH CH2)2] OH2, prepared in a one pot procedure from Alloc-Ser-OH, was introduced at the N-terminus of a sequence prepared by standard Fmoc-SPPS. Global cleavage of the allyl ester based protecting groups, followed by coupling of a tripeptide fragment, led to the tau phosphopeptide, 1. Using tau phosphopeptides a series of phosphorylation state-dependent antisera to human tau protein have been raised. These antisera are valuable tools for studying the tau protein which is found in an abnormal, hyperphosphorylated form in Alzheimer's disease brain.

Abstract
We have studied the effects of peptide aldehyde protease inhibitors on the secretion of beta-amyloid peptide 1-40 (Abeta(1-40)) and Abeta(1-42) by HEK 293 and COS-1 cells expressing beta-amyloid precursor protein with the Swedish double mutation. A multiphasic SDS-polyacrylamide gel electrophoresis system was used for the discrimination of Abeta(1-40) and Abeta(1-42). Calpain inhibitor I, carbobenzoxyl-Leu-Leu-leucinal, and calpeptin were found to reduce the amount of Abeta(1-40) released into the medium in a dose-dependent manner. The reduction of Abeta(1-40) after treatment with 50 microM calpain inhibitor I or 5 microM carbobenzoxyl-Leu-Leu-leucinal was accompanied by a slight increase of Abeta(1-42) released into the medium. These observations suggest that the cleavages at residues 40 and 42 are accomplished by different enzyme activities.

Abstract
The secondary structures of peptides beta 25-35 (the active toxic fragment) and beta 35-25 (reverse sequence and non-toxic fragment), as well as of the amidated beta (25-35)-NH2 peptide were investigated in aqueous solution and in the solid state by means of Fourier-transformed infrared spectroscopy and circular dichroism spectroscopy. The conformations of the beta 25-35 and beta 35-25 in solid state were identical and contained mostly beta-sheet structures. In solid state the amidated beta (25-35)-NH2 peptide also contained mostly beta-sheet structures. Freshly prepared aqueous solutions of the beta 25-32 (0.5 - 3.8 mM) contained a mixture of beta-sheet and random coil structures. Within 30-60 min incubation at 37 degrees C in water or in phosphate-buffered saline solution (PBS), beta 25-35 was almost fully converted to a beta-sheet structure. Decreasing the temperature from 37 degrees C to 20 degrees C decreased the rate of conversion from random coil to beta-sheet structures, 1-2 h being required for complete conversion. In contrast beta 35-25 in water or in PBS buffer had mostly a random coil structure and remained so for 6 days. The amidated beta(25-35)-NH2 peptide in water (2.7 mM) was also mostly random coil. However, when this peptide (2-2.7 mM) was dissolved in PBS (pH 7.4) or in 140 mM NaCl, a gel was formed and its conformation was mostly beta-sheet. Decreasing the concentration of beta (25-35)-NH2 peptide in 140 mM NaCl aqueous solution from 2 mM to 1 mM or below favored the conversion from beta-sheet structures to random coil structures. The beta 25-35 was toxic to PC12 cells while beta 35-25 was not. The amidated peptide beta (25-35)-NH2 was at least 500-fold less toxic than beta 25-35. Structural differences between these beta peptides in aqueous solutions may explain the difference in their respective toxicities.

Abstract
We have investigated the effects of the C-terminal amyloid precursor protein fragment His 657-Lys 676 upon calcium currents in NG108-15 neuroblastoma x glioma hybrid cells. The amyloid precursor protein fragment His 657-Lys 676 (1-10 microM) did not affect calcium currents per se, but clearly blocked the calcium current suppression mediated by both adrenergic alpha 2B- and opioid delta receptors in a concentration-dependent manner. The reverse amyloid precursor protein fragment Lys 676-His 657 and the shorter amyloid precursor protein fragment Gly 659-Lys 676 did not affect calcium current suppression by adrenergic alpha 2B- and opioid delta receptors. The similar interaction of C-terminal amyloid precursor protein with adrenergic alpha 2B- and opioid delta receptors suggest that the effect occurs downstream of the receptor, possibly via the GTP binding protein Go.

Abstract
Four proteins from Candida albicans extracts have been isolated by ATP affinity chromatography. These proteins were found to be at elevated levels in extracts of cells raised from 25 degrees C to 37 degrees C, but were present at low levels in cells grown at 25 degrees C. The molecular masses of the proteins (38-42 kDa, 66-68 kDa, 70-72 kDa and 74-76 kDa) correspond to the published sizes of C. albicans heat-shock proteins. Three of the four proteins were recognized by the sera of patients with oral and/or oesophageal C. albicans infections, with the 70-72 kDa protein reacting in all cases tested. Binding of antibodies to two of the other proteins (38-42 kDa and 74-76 kDa) differed from patient to patient. IgA antibodies were the dominant immunoglobulin class in these mucosal C. albicans infections. The IgA antibody titre may be of diagnostic value and seemed to be correlated to the severity of infections, with a higher level in oesophageal infections compared to oral infections. Antibody binding to these proteins was specific as the sera did not show the same enhanced recognition with bacterial or HeLa cell heat-shock proteins.

Abstract
Resting T lymphocytes can be induced to express a variety of lymphokines after antigenic or mitogenic stimulation. Expression is regulated both at the transcriptional level, through induction of T cell-specific DNA-binding proteins, and at the post-transcriptional level through alteration of precursors or mRNA stability. To investigate whether lymphokine expression follows a preprogrammed course after activation of T cells or whether it is dependent on the continued monitoring of activating signals, we followed the fate of interleukin (IL) 2, IL 4 and IL 2 receptor mRNA after removal of the stimulating signal concanavalin (Con A) by alpha-methylmannoside (alpha MM). IL 2 and IL 4 needed continued stimulation of the cells for RNA expression, as shown by the rapid disappearance of IL 2 and IL 4 mRNA after addition of alpha MM to stimulated cells, while IL 2 receptor mRNA which is also induced after Con A stimulation was minimally influenced. In the case of both IL no new mature mRNA was generated after removal of the stimulating signal. The T1/2 of IL 2 mRNA remained unchanged after alpha MM treatment as compared to actinomycin D treatment, while IL 4 mRNA became labilized after withdrawal of the signal.

Abstract
Tonsils of 50 patients with infectious mononucleosis were examined for the presence of Epstein-Barr virus nuclear antigens (EBNA) and in 11 cases for the presence of Epstein-Barr virus (EBV) nucleic acid sequences. In tonsillar tissue of 42 patients less than 1 to 40 per cent EBNA-positive cells could be demonstrated by anticomplement immunofluorescence. 10 out of 11 tonsils examined by in situ hybridization contained less than 1 to 50 per cent cells with EBV nucleic acid sequences. The histological examination indicated that cells labelled by in situ hybridisation are in the majority proliferating B-lymphocytes and to a small extent cells of tonsillar epithelium.

Abstract
The immediate upstream region of the mouse interleukin 2 (Il-2) gene harbors a strong transcriptional enhancer. This enhancer contains most, if not all of the sequence elements necessary for the T cell specific induction of the Il-2 gene by the phorbol ester TPA and the plant lectin Concanavalin A. DNase I footprinting studies with fractionated extracts obtained from induced and uninduced E14 T cells revealed numerous recognition sites for potential trans-acting factors. Five of these sites are also recognized by the TPA-activated HeLa cell factors AP-1 and AP-3. Other sites including two TATA-boxes, two purine-rich sequence motifs and two copies of the GGGPuTTTCAA motif are recognized by lymphocyte specific factors. The latter motif is highly conserved between several lymphokine genes and is therefore designated as a T cell element (TCE). In E14 T cells, pentamers of the distal TCEd confer an activity similar to that of the entire Il-2 enhancer, whereas in B and HeLa cells, the TCEd-pentamer is inactive as is the Il-2 enhancer. These data indicate the involvement of the TCEd and its recognition factor(s) in the cell type specific induction of the Il-2 gene during T cell activation.

Abstract
In mitogen-stimulated mouse spleen cells, the IL 2 gene is only transiently expressed with maximal mRNA steady state levels between 6-14 h post stimulation with Concanavalin A (Con A). This is also reflected by the kinetics of IL 2 release into culture supernatants. Con A-stimulated L3T4+ and Lyt2+ T cell subpopulations express the IL 2 gene and produce IL 2 similarly. The half-life of IL 2 mRNA is only 30 min, but can be prolonged significantly by cycloheximide. At later post stimulation times IL 2 gene transcription is reduced, as indicated by the reduced effect of cycloheximide. IL 2 gene expression is not influenced by added IL 2 or IFN-gamma.

Abstract
The conditions of in situ hybridization for demonstration of herpesvirus genomes in animal and human tissues were tested using the ORWO(R) K6 emulsion. It was possible to localize herpes simplex virus (HSV) genomes in infected mice organs (brain and liver) as well as Epstein-Barr virus (EBV) genomes in tonsils of patients with infectious mononucleosis and in tumour specimens of patients with nasopharyngeal carcinomas. Immunofluorescence (IF) revealed mostly corresponding results. The in situ hybridization is more favourable due to its higher specifity, but it is more time consuming and expensive. IF seems advantageous for screening of a great number of tissues.

Abstract
In the present study, the clinical course and the specific humoral immunological response to Epstein-Barr virus antigens have been investigated in patients affected with infectious mononucleosis after tonsillectomy in the acute phase of the disease, compared against conservatively treated patients. Clinical results confirm that tonsillectomy in the acute phase of infectious mononucleosis has a favourable effect on the course of the disease, and reduces the duration of the disease by about half of the usual time. Statistically significant differences - indicating a confined, delayed humoral immunological response or unresponsiveness to some extent - regarding the examined antigens after tonsillectomy in the acute phase of infectious mononucleosis, could be observed between the two groups of patients in respect of the production of antibodies against viral capsid and nuclear antigens of the Epstein-Barr virus and heterophilic antibodies. For this reason, tonsillectomy should be suggested only as therapy of infectious mononucleosis in anginous courses of the disease which appear life-threatening.
