The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.

Plasma-soluble CD30 in childhood tuberculosis: effects of disease severity, nutritional status, and vitamin A therapy. (1/479)

Plasma-soluble CD30 (sCD30) is the result of proteolytic splicing from the membrane-bound form of CD30, a putative marker of type 2 cytokine-producing cells. We measured sCD30 levels in children with tuberculosis, a disease characterized by prominent type 1 lymphocyte cytokine responses. We postulated that disease severity and nutritional status would alter cytokine responses and therefore sCD30 levels. Samples from South African children enrolled prospectively at the time of diagnosis of tuberculosis were analyzed. (Patients were originally enrolled in a randomized, double-blind placebo-controlled study of the effects of oral vitamin A supplementation on prognosis of tuberculosis.) Plasma samples collected at the time of diagnosis and 6 and 12 weeks later (during antituberculosis therapy) were analyzed. sCD30 levels were measured by enzyme immunoassay. The 91 children included in the study demonstrated high levels of sCD30 at diagnosis (median, 98 U/liter; range, 11 to 1,569 U/liter). Although there was a trend toward higher sCD30 levels in more severe disease (e.g., culture-positive disease or miliary disease), this was not statistically significant. Significantly higher sCD30 levels were demonstrated in the presence of nutritional compromise: the sCD30 level was higher in patients with a weight below the third percentile for age, in those with clinical signs of kwashiorkor, and in those with a low hemoglobin content. There was minimal change in the sCD30 level after 12 weeks of therapy, even though patients improved clinically. However, changes in sCD30 after 12 weeks differed significantly when 46 patients (51%) who received vitamin A were compared with those who had received a placebo. Vitamin A-supplemented children demonstrated a mean (+/- standard error of the mean) decrease in sCD30 by a factor of 0.99 +/- 0.02 over 12 weeks, whereas a factor increase of 1.05 +/- 0.02 was demonstrated in the placebo group (P = 0.02). We conclude that children with tuberculosis had high sCD30 levels, which may reflect the presence of a type 2 cytokine response. Nutritional compromise was associated with higher sCD30 levels. Vitamin A therapy resulted in modulation of sCD30 levels over time. (+info)

Autologous stem cell transplantation for T and null cell CD30-positive anaplastic large cell lymphoma: analysis of 64 adult and paediatric cases reported to the European Group for Blood and Marrow Transplantation (EBMT). (2/479)

Anaplastic large cell lymphoma (ALCL) is a heterogeneous family of lymphoid tumours, among which the T and null cell types were recently listed in the REAL classification as a distinct entity. Reports on autologous stem cell transplantation (ASCT) in this group are only occasional. Sixty-four patients with T and null cell ALCL from 25 European centres had been registered with the European Group for Blood and Marrow Transplantation (EBMT) at the onset of this study. The median age was 25 years (range 3.2-53.0). Thirty of the 64 patients (47%) were in complete remission (CR), 18 (28%) in partial remission (PR), and the remaining 16 (25%) had a more advanced or chemotherapy-refractory disease at transplant. Eighty-one percent of the patients were conditioned with chemotherapy alone and 75% received marrow stem cells. All the patients transplanted in first CR (15), except one, maintained the CR over time; six of 15 transplanted in CR subsequent to first, six of 18 transplanted in PR and 14 of 16 transplanted in refractory or relapsed disease progressed. Actuarial overall survival (OS) at 10 years is 70%. Multivariate analysis showed that good status at transplant, younger age, absence of B symptoms and absence of extranodal disease indicated a better prognosis. These data suggest that ASCT should be considered as a possible treatment for chemosensitive patients in CR or PR. However, definitive conclusions cannot be drawn from this study and a prospective randomised trial between ASCT and conventional chemotherapy may be indicated. (+info)

ALK+ lymphoma: clinico-pathological findings and outcome. (3/479)

A distinct pathologic entity (ALK+ lymphoma) that is characterized by expression of the anaplastic lymphoma kinase (ALK) protein has recently emerged within the heterogeneous group of CD30(+) anaplastic large-cell lymphomas. Information on clinical findings and treatment outcome of ALK+ lymphoma is still limited, and no data are available concerning the value of the International Prognostic Index when applied to this homogeneous disease entity. To clarify these issues, a recently developed monoclonal antibody ALKc (directed against the cytoplasmic portion of ALK) was used to detect expression of the ALK protein in paraffin-embedded biopsies from 96 primary, systemic T/null anaplastic large-cell lymphomas, and the ALK staining pattern was correlated with morphological features, clinical findings, risk factors (as defined by the International Prognostic Index), and outcome in 78 patients (53 ALK+ and 25 ALK-). Strong cytoplasmic and/or nuclear ALK positivity was detected in 58 of 96 ALCL cases (60.4%), and it was associated with a morphological spectrum (common type, 82.7%; giant cell, 3.5%; lymphohistiocytic, 8. 6%; and small cell, 5.2%) that reflected the ratio of large anaplastic elements (usually showing cytoplasmic and nuclear ALK positivity) to small neoplastic cells (usually characterized by nucleus-restricted ALK expression). Clinically, ALK+ lymphoma mostly occurred in children and young adults (mean age, 22.01 +/- 10.87 years) with a male predominance (male/female [M/F] ratio, 3.0) that was particularly striking in the second-third decades of life (M/F ratio, 6.5) and usually presented as an aggressive, stage III-IV disease, frequently associated with systemic symptoms (75%) and extranodal involvement (60%), especially skin (21%), bone (17%), and soft tissues (17%). As compared with ALK+ lymphoma, ALK- cases occurred in older individuals (mean age, 43.33 +/- 16.15 years) and showed a lower M/F ratio (0.9) as well as lower incidence of stage III-IV disease and extranodal involvement at presentation. Overall survival of ALK+ lymphoma was far better than that of ALK- anaplastic large-cell lymphoma (71% +/- 6% v 15% +/- 11%, respectively). However, within the good prognostic category of ALK+ lymphoma, survival was 94% +/- 5% for the low/low intermediate risk group (age-adjusted International Prognostic Index, 0 to 1) and 41% +/- 12% for the high/high intermediate risk group (age-adjusted International Prognostic Index, >/=2). Multivariate analysis identified ALK expression and the International Prognostic Index as independent variables that were able to predict survival among T/null primary, systemic anaplastic large-cell lymphoma. Thus, we suggest that such parameters should be taken into consideration for the design of future clinical trials. (+info)

The T-cell activation markers CD30 and OX40/CD134 are expressed in nonoverlapping subsets of peripheral T-cell lymphoma. (4/479)

The tumor necrosis factor (TNF) receptor family includes several important markers of activation in T cells. We examined expression patterns of two T-cell-associated members of these receptors, namely CD30 and OX40/CD134, in 148 cases of T-cell lymphoma to identify possible objective immunohistochemical criteria for subclassification of these tumors. CD30 expression was characteristic of tumors with an anaplastic (46/47 cases [98%]) or large-cell (10/21 [48%]) morphology and was seen in only scattered cells in other tumor types. In contrast, large numbers of OX40/CD134(+) tumors cells were typical of angioimmunoblastic lymphoma (15/16 [94%]), angiocentric lymphoma (4/4), a subset of large-cell lymphomas (10/21 [48%]), and lymphomas with a prominent histiocytic component (6/7 [86%]). Strong OX40/CD134 and CD30 coexpression was seen in only 4% of tumors, typically those with an anaplastic/Hodgkin's-like appearance. OX40/CD134 expression was characteristic of tumors composed of activated CD4(+) T cells and was not seen in small-cell T-cell lymphomas, lymphoblastic lymphomas, or other tumor types, including B-cell lymphomas or carcinomas. These results suggest that immunostaining for OX40/CD134 may be helpful in subclassification of peripheral T-cell lymphomas and that the patterns of TNF receptor family expression in these tumors may parallel those seen within nonneoplastic helper T-cell subsets.

Induction of cell death by tumour necrosis factor (TNF) receptor 2, CD40 and CD30: a role for TNF-R1 activation by endogenous membrane-anchored TNF. (5/479)

Several members of the tumour necrosis factor receptor (TNF-R) superfamily can induce cell death. For TNF-R1, Fas/APO-1, DR3, DR6, TRAIL-R1 and TRAIL-R2, a conserved 'death domain' in the intracellular region couples these receptors to activation of caspases. However, it is not yet known how TNF receptor family members lacking a death domain, such as TNF-R2, CD40, LT-betaR, CD27 or CD30, execute their death-inducing capability. Here we demonstrate in different cellular systems that cytotoxic effects induced by TNF-R2, CD40 and CD30 are mediated by endogenous production of TNF and autotropic or paratropic activation of TNF-R1. In addition, stimulation of TNF-R2 and CD40 synergistically enhances TNF-R1-induced cytotoxicity. These findings describe a novel pro-apoptotic mechanism induced by some members of the TNF-R family.

An anti-CD30 single-chain Fv selected by phage display and fused to Pseudomonas exotoxin A (Ki-4(scFv)-ETA') is a potent immunotoxin against a Hodgkin-derived cell line. (6/479)

The human CD30 receptor is highly overexpressed on the surface of Hodgkin Reed-Sternberg cells and has been shown to be an excellent target for selective immunotherapy using monoclonal antibody-based agents such as immunotoxins. To construct a new recombinant immunotoxin for possible clinical use in patients with Hodgkin's lymphoma, we have chosen the murine anti-CD30 hybridoma Ki-4 to generate a high-affinity Ki-4 single-chain variable fragment (scFv). Hybridoma V-genes were polymerase chain reaction-amplified, assembled, cloned and expressed as a mini-library for display on filamentous phage. Functional Ki-4 scFv were obtained by selection of binding phage on the Hodgkin lymphoma-derived, CD30-expressing cell line L540Cy. The selected recombinant Ki-4 scFv was shown to specifically bind to an overlapping epitope on the CD30 antigen with binding kinetics similar to those of the original antibody. The Ki-4 scFv was subsequently fused to a deletion mutant of Pseudomonas exotoxin A (ETA'). The resulting immunotoxin Ki-4(scFv)-ETA' specifically binds to CD30+ L540Cy cells and inhibits the protein synthesis by 50% at a concentration (IC50) of 43 pM. This recombinant immunotoxin is a promising candidate for further clinical evaluation in patients with Hodgkin's lymphoma or other CD30+ malignancies. (+info)

CD30 overexpression enhances negative selection in the thymus and mediates programmed cell death via a Bcl-2-sensitive pathway. (7/479)

The biological function of CD30 in the thymus has been only partially elucidated, although recent data indicate that it may be involved in negative selection. Because CD30 is expressed only by a small subpopulation of medullary thymocytes, we generated transgenic (Tg) mice overexpressing CD30 in T lymphocytes to further address its role in T cell development. CD30 Tg mice have normal thymic size with a normal number and subset distribution of thymocytes. In vitro, in the absence of CD30 ligation, thymocytes of CD30 Tg mice have normal survival and responses to apoptotic stimuli such as radiation, dexamethasone, and Fas. However, in contrast to controls, CD30 Tg thymocytes are induced to undergo programmed cell death (PCD) upon cross-linking of CD30, and the simultaneous engagement of TCR and CD30 results in a synergistic increase in thymic PCD. CD30-mediated PCD requires caspase 1 and caspase 3, is not associated with the activation of NF-kappaB or c-Jun, but is totally prevented by Bcl-2. Furthermore, CD30 overexpression enhances the deletion of CD4+/CD8+ thymocytes induced by staphylococcal enterotoxin B superantigen and specific peptide. These findings suggest that CD30 may act as a costimulatory molecule in thymic negative selection. (+info)

IL-12 receptor beta2 and CD30 expression in paranasal sinus mucosa of patients with chronic sinusitis. (8/479)

The aetiology of chronic sinusitis is still poorly understood. The expression of T-helper 1 (Th1) and T-helper 2 (Th2) cell markers, interleukin (IL)-12 receptor beta2 subunit (IL-12Rbeta2) messenger ribonucleic acid (mRNA) and CD30, respectively, were investigated in the paranasal sinus mucosa of patients with chronic sinusitis in an attempt to elucidate the involvement of Th1 and Th2 cells in this disease. Anterior ethmoidal mucosae were surgically obtained from two groups of patients with chronic sinusitis: those who had allergic rhinitis (allergic group, n=11) and those without allergy (nonallergic group, n=11). IL-12Rbeta2 mRNA was quantified by means of the reverse transcription polymerase chain reaction, and CD30-positive cells were examined immunohistochemically. Both IL-12Rbeta2 mRNA and CD30 were expressed in the sinus mucosa of the allergic and nonallergic groups. The proportion of mononuclear cells which were CD30-positive in the sinus mucosa was significantly greater in the allergic than in the nonallergic group. The expression levels of IL-12Rbeta2 mRNA were virtually equivalent in both groups. These results suggest a T-helper 2-dominated mucosal reaction in the allergic compared to the nonallergic group, and indicate T-helper 1 activity in the sinus mucosa of both groups. The ubiquity of T-helper 1 cells suggests that they play a role in maintaining local mucosal defences against foreign antigens, which continually enter the upper respiratory tract. (+info)
