Disease relevance of Passive Cutaneous Anaphylaxis

• In this study, spontaneous procoagulant activity (PCA) was measured in circulating mononuclear cells to determine whether elevated PCA correlated with the presence of proliferative glomerulonephritis in patients with systemic lupus erythematosus (SLE) [1].
• The PCA response was antigen specific: peripheral blood mononuclear cells (PBM) from donors sensitive to PPD or tularemia showed an increase in PCA only in response to the sensitizing antigen [2].
• The binding properties and the regional densities of histamine H(1) receptors were studied in brain of rats with portacaval anastomosis (PCA) and in autopsied brain tissue from cirrhotic patients with hepatic encephalopathy (HE) [3].
• This project was undertaken to study the survival properties of various prostate cells, including normal (NHP), BPH (benign prostate hyperplasia), primary carcinoma (PCA), and metastatic prostate cancer cells (LNCaP, PC3, and Du145), in the absence of trophic factors [4].
• IgE injected i.p. 24 hr before the sensitization with IgE anti-ovalbumin (OVA) completely inhibited both IgE- and IgG2a-induced passive cutaneous anaphylactic (PCA) reactions at a dose (2.5 mg/100 g body weight) that resulted in peak serum concentrations of 150 micrograms IgE IR162/ml [5].

• The levels of PCA, TNF-alpha, and IL-6 obtained with plasma from shock patients were not different from those induced by plasma from 10 meningococcal patients without shock or with plasma from healthy persons [11].

• The magnitude of the monocyte PCA response increased in response to an increase in the allogeneic stimulator/T clone responder ratio, and third-party allogeneic cells were unable to elicit the PCA-inducing lymphokine signals from T inducer clones [13].
• In eight patients with SLE but with no apparent active renal disease, PCA was not elevated above normal basal levels [1].

Chemical compound and disease context of Passive Cutaneous Anaphylaxis

• The temporal relationships of macrophage accumulation, glomerular fibrin deposition, the expression of glomerular procoagulant activity (PCA), and Factor VIII antigen deposition were studied in rabbits in which antiglomerular basement membrane antibody-induced glomerulonephritis (anti-GBM GN) developed [14].
• An antigen has been isolated from a human signet-ring cell carcinoma serially growing in hamsters, GW-39, by saline, PCA, or phenol extraction, and has been found immunologically identical to a similarly extracted substance in normal human or hamster colon [15].
• We have found that penicillic acid (PCA) inhibits FasL-induced apoptosis and concomitant loss of cell viability in Burkitt's lymphoma Raji cells [16].
• We therefore studied the effects of ribavirin on murine hepatitis virus strain 3 replication, macrophage production of proinflammatory mediators including TNF, IL-1, and the procoagulant activity (PCA), fgl2 prothrombinase; and Th1/Th2 cytokine production [17].
• The severity of the systemic anaphylactic reactions correlated significantly with the titers of either 8-day passive cutaneous anaphylactic (8-day PCA) reactions or 4-hr PCA reactions evoked with the same benzylpenicillin preparations [18].

Biological context of Passive Cutaneous Anaphylaxis

• The kinetics of the endothelial PCA responses to TNF and IL-1 were similar, demonstrating a rapid rise to peak activity at approximately equal to 4 hr, and a decline toward basal levels by 24 hr [19].
• These multiple effects on cholesterol homeostasis and pool sizes strongly suggest that PCA can reverse the progressive accumulation of cholesterol in body tissues of FH patients [20].
• Cell differentiation in a myeloid direction induced by retinoic acid or DMSO led to a diminished PCA, while not affecting the fibrinolytic activity [21].
• Dietary administration of PCA also caused significant decreases in the labeling index of bromodeoxyuridine and the number and area of silver-stained nucleolar organizer regions per cell nucleus, known as cell proliferation indices, of the tongue squamous epithelium (P < 0.05) [22].
• A serially transplantable, primary human PCA, designated CWR22, exhibits a clonal cytogenetic aberration, causes high elevations of prostate specific antigen in the peripheral blood of nude mice, and is unusually responsive to androgen deprivation as compared with other xenografts [23].

Anatomical context of Passive Cutaneous Anaphylaxis

• The median levels of PCA, TNF-alpha, and IL-6 were 5, 0, and 4%, respectively, of the monocyte activities induced by normal plasma boosted with purified N. meningitidis (Nm)-LPS (2,500 pg/ml; net LPS-boosted capacity, 100%) [11].
• Induction of PCA by rTNF was concentration dependent (maximum, 500 units/ml), time dependent, reversible, and blocked by cycloheximide and actinomycin D, and it occurred without detectable endothelial cell damage [19].

• In all four dogs who escaped from DOCA, the PCA was widely patent and the mean pressure gradient was only 1.6 cm H2O [27].
• In addition, PCA caused a net efflux of accumulated tissue cholesterol as demonstrated by reductions in the rapidly exchangeable and total exchangeable masses of body cholesterol [20].
• We conclude that YFP PCA can detect weak and transient protein interactions in the secretory pathway and hence is a powerful approach to study luminal processes involved in protein secretion [28].
