Peritoneal Mast Cells

Presence of mast cell precursors in the mouse peritoneal cavity was demonstrated, and the precursors were characterized. When a cell suspension, containing mast cell precursor(s), was directly injected into the skin of genetically mast cell-deficient WBB6F1 (WB X C57BL/6)-W/Wv mice, a cluster composed of approximately 2,000 mast cells appeared at the injection site. By determining the proportion of injection sites at which the mast cell cluster appeared, the concentration of mast cell precursors can be calculated by limiting dilution analysis. The concentration in the peritoneal cavity was about five times as great as the concentration in the bone marrow. Although peritoneal mast cell precursors were shown to originate from the bone marrow, physical characterization revealed that the peritoneal precursors differed from the marrow precursors. The peritoneal precursors were less susceptible to irradiation than the marrow precursors; the former were heavier than the latter. When a 95% pure mast cell suspension was prepared from the peritoneal cells by the removal of phagocytes and the density gradient centrifugation, 1 out of 16 cells had the potentiality to make a mast cell cluster in the skin of the W/Wv mice. Moreover, when a single mast cell was identified under the phase contrast microscope and picked up with the micromanipulator, 1 out of 17 mast cells made the cluster. This indicated that some peritoneal mast cells kept extensive proliferative potentiality even after morphological differentiation. In other words, some peritoneal mast cells themselves may function as the committed precursors.

Abstract Two different types of cells in the peritoneal cavity of mice produce mast cell colonies in methylcellulose. “Large” mast cell colonies are produced by bone marrow-derived precursors resembling lymphoid cells by light microscopy (L-CFU-Mast), whereas “medium” and “small” mast cell colonies are produced by morphologically identifiable mast cells (M-CFU- Mast and S-CFU-Mast, respectively). In the present study we eradicated peritoneal mast cells by intraperitoneal (IP) injection of distilled water. The regeneration process was investigated to clarify the relationship between L-CFU-Mast, M-CFU-Mast, and S-CFU-Mast. After injection of distilled water, M-CFU-Mast and S-CFU-Mast disappeared, but L-CFU-Mast increased, and then M-CFU-Mast and S-CFU-Mast appeared, suggesting the presence of a hierarchic relationship. When purified peritoneal mast cells were injected two days after the water injection, the L-CFU-Mast did not increase. In the peritoneal cavity of WBB6F1-+/+ mice that had been lethally irradiated and rescued by bone marrow cells of C57BL/6-bgJ/bgJ (beige, Chediak-Higashi syndrome) mice, L-CFU-Mast were of bgJ/bgJ type, but M-CFU-Mast and S-CFU-Mast were of +/+ type. The injection of distilled water to the radiation chimeras resulted in the development of bgJ/bgJ-type M-CFU-Mast and then S-CFU-Mast. The presence of mast cells appeared to suppress the recruitment of L-CFU- Mast from the bloodstream and to inhibit the differentiation of L-CFU- Mast to M-CFU-Mast.

Both connective tissue mast cells and mast cells grown in vitro are derived from multipotential hematopoietic stem cells, but these two mast cell populations exhibit many differences in morphology, biochemistry, and function. We investigated whether the phenotype of cultured mast cells or their progeny was altered when the cells were transferred into different locations in vivo. Cultured mast cells were immature by ultrastructure, and stained with alcian blue but with neither safranin or berberine sulfate, a fluorescent dye that binds to the heparin of connective tissue mast cell granules. By contrast, mast cells recovered from the peritoneal cavity of congenitally mast cell-deficient (WB X C57BL/6)F1-W/Wv (WBB6F1-W/Wv) mice 10 wk after intraperitoneal injection of cultured WBB6F1-+/+ or C57BL/6-bgJ/bgJ mast cells stained with both safranin and berberine sulfate. Staining with berberine sulfate was prevented by treatment of the cells with heparinase but not chondroitinase ABC, suggesting that the adoptively transferred mast cell population had acquired the ability to synthesize and store heparin. Furthermore, the recovered mast cells were indistinguishable by ultrastructure from the normal mature peritoneal mast cells of WBB6F1-+/+ mice, and contained substantially more histamine than mast cells studied directly from culture. Intravenous injection of cultured mast cells resulted in the development of safranin-and berberine sulfate-positive mast cells in the peritoneal cavity, spleen, skin, and glandular stomach muscularis propria. Mast cells also developed on the glandular stomach mucosa, but these cells stained with alcian blue rather than safranin, and did not stain with berberine sulfate. This result suggests that cultured mast cells can give rise to mast cells of either the connective tissue type or mucosal phenotype, depending on anatomical location. Furthermore, transplantation of cultured mast cells into WBB6F1-W/Wv mice had no measurable effect on the anemia of the recipient mice, suggesting a possible strategy for repairing the mast cell deficiency of WBB6F1-W/Wv mice without affecting other bone marrow-derived populations such as erythrocytes. Intravenous injection of representative connective tissue type mast cells (30-50% pure peritoneal mast cells derived from WBB6F1-+/+ mice) gave results similar to those obtained with cultured mast cells: mast cells developing in the peritoneal cavity, skin, spleen, and glandular stomach muscularis propria of WBB6F1-W/Wv recipients stained with safranin and berberine sulfate, whereas mast cells developing in the mucosa of the glandular stomach stained only with alcian blue.(ABSTRACT TRUNCATED AT 400 WORDS)

Background: Pituitary adenylate cyclase activating peptide-38 (PACAP-38) has been shown to induce migraine in migraineurs, whereas the related peptide vasoactive intestinal peptide (VIP) does not. In the present study we examine the hypothesis that PACAP-38 and its truncated version PACAP-27 but not VIP cause degranulation of mast cells in peritoneum and in dura mater. Methods: The degranulatory effects of PACAP-38, PACAP-27 and VIP were investigated by measuring the amount of N-acetyl-β-hexosaminidase released from isolated peritoneal mast cells and from dura mater attached to the skull of the rat in vitro. In peritoneal mast cells N-truncated fragments of PACAP-38 (PACAP(6–38), PACAP(16–38) and PACAP(28–38)) were also studied. To investigate transduction pathways involved in mast cell degranulation induced by PACAP-38, PACAP-27 and VIP, the phospholipase C inhibitor U-73122 and the adenylate cyclase inhibitor SQ 22536 were used. Results: The peptides induced degranulation of isolated peritoneal mast cells of the rat with the following order of potency: PACAP-38 = PACAP(6–38) = PACAP(16–38) » PACAP-27 = VIP = PACAP(28–38). In the dura mater we found that 10−5 M PACAP-38 was significantly more potent in inducing mast cell degranulation than the same concentration of PACAP-27 or VIP. Inhibition of intracellular mechanisms demonstrated that PACAP-38-induced degranulation is mediated by the phospholipase C pathway. Selective blockade of the PAC1 receptor did not attenuate degranulation. Conclusion: These findings correlate with clinical studies and support the hypothesis that mast cell degranulation is involved in PACAP-induced migraine. PACAP-38 has a much stronger degranulatory effect on rat peritoneal and dural mast cells than VIP and PACAP-27. The difference in potency between PACAP-38- and PACAP-27/VIP-induced peritoneal mast cell degranulation is probably not related to the PAC1 receptor but is caused by a difference in efficacy on phospholipase C.

Abstract Mast cells are hematopoietic cells localized in extramedullary sites where they engage themselves in the process of allergic response and in the immune reaction against parasites. Mast cells derive from multilineage c-KitlowCD34lowSca-1pos progenitor cells present in the marrow. These cells give rise to Linnegc-KitposSca-1neg T1/ST2pos mast cell restricted progenitor cells (MCP) whose futher maturation in the marrow remains limited under steady state conditions. MCP migrate through the blood in extramedullary sites were they mature into tissue-retricted c-KitposFceRIpos mast cells characterized by a specific mast cell protease (MMCP) profiling (dermal, mucosal and serosal mast cells in skin, gut and peritoneal cavity, respectively). The molecular mechanism that, in normal mice, restricts the mastocytopoietic potential of progenitor cells to the extramedullary sites, as well as the factors that guide the tissue-restricted differentiation of these cells, are unknown. Thrombopoietin (TPO)-Mpl interactions play an important role in the regulation of hematopoietic stem/progenitor cell proliferation and differentiation in the marrow. Here we report that mast cells, and their precursors, express Mpl (both as mRNA and cell surface protein) (see Table). Furthermore, targeted deletion of this gene (Mplnull mutation) decrease the number of MCP (by 1-log) and increases that of mast cells in dermis (by 3-fold), peritoneal cavity (by 3-fold), bone marrow (2-log) and spleen (2-log). Furthermore, because of their higher (by 2-log) MMCP-7 expression, serosal Mplnull mast cells resemble more wild-type dermal rather than serosal mast cells. On the other hand, either treatment of mice with TPO or addition of TPO to bone marrow-derived mast cell cultures induces mast cell apoptosis (by Tunel and Annexin staining) and severely hampers mast cell differentiation (by expression profiling). These data are consistent with a regulatory mechanism for murine mastocytopoiesis according to which TPO favours the transition from multilineage progenitors to CMP but blocks differentiation of MCP to mature mast cells. We propose TPO as the growth factor that restrict mast cell differentiation to extramedullaty sites and that control the switch between serosal vs dermal mast cell differentiation.

To determine whether changes in membrane potential affect the extent of mast cell degranulation, compound 48/80 was added to rat peritoneal mast cell suspensions in the absence or presence of potassium channel openers (KCOs). Changes were compared between the field potential (FP) and the amount of histamine released. The results demonstrated that (i) the onset and duration of FP, which reflects the hyperpolarizing nature of the response, increased as the concentration of compound 48/80 increased; (ii) both FP and the amount of histamine released increased as the concentration of compound 48/80 increased; (iii) although both KCOs (SDZ PCO400, a benzopyran derivative, and P1060, a cyanoguanidine derivative) potentiated compound 48/80-induced increases in FP and histamine release, without compound 48/80, they had no effect on either parameter; (iv) both glibenclamide and charybdotoxin significantly attenuated the compound 48/80-induced increase in FP; and (v) glibenclamide was able to attenuate the KCO-induced potentiation of FP. The results show that drugs presumably causing hyperpolarization can affect histamine release from rat peritoneal mast cells. The effect of KCOs on compound 48/80-induced response appears to be potentiation in nature rather than synergism. It is possible that KCO hyperpolarizes the cell membrane, enhances Ca2+ influx, and thus increases histamine release. As such, selective blockers of K+ channels may be useful for the treatment of immunological disorders.

Purified perigranular and plasma membranes isolated from rat peritoneal mast cells were examined for Ca2+- and Mg2+-dependent ATPase activity. Isolated perigranular membranes contained only a low-affinity Ca2+- or Mg2+-dependent ATPase (Km greater than 0.5 mM). The plasma membranes contained both a low-affinity Ca2+- or Mg2+-dependent ATPase (Km = 0.4 mM, Vmax. = 20 nmol of Pi/min per mg), as well as a high-affinity Ca2+- and Mg2+-dependent ATPase (Km = 0.2 microM, Vmax. = 6 nmol of Pi/min per mg).

BackgroundThe role of mast cells accumulating in idiopathic pulmonary fibrosis (IPF) lungs is unknown.ObjectivesWe investigated the effect of fibrotic extracellular matrix (ECM) on mast cells in experimental and human pulmonary fibrosis.ResultsIn IPF lungs, mast cell numbers were increased and correlated with disease severity (control vs 60%<FVC<90%, mean difference=-222.7, 95% CI −386.3 to −59.2, p=0.004; control vs FVC<60%, mean difference=−301.7, 95% CI of difference −474.1 to −129.34, p=0.0001; FVC>90% vs 60%<FVC<90%, mean difference=−189.6, 95% CI of difference −353.1 to −26.03, p=0.017; FVC>90% vs FVC<60%, mean difference=−268.6, 95% CI of difference −441.0 to −96.17, p=0.0007). Plasma tryptase levels were increased in IPF and negatively correlated with FVC (control vs FVC<60%, mean difference=−17.12, 95% CI of difference −30.02 to −4.22, p=0.006: correlation curves R=−0.045, p=0.025). In a transforming growth factor (TGF)-β1-induced pulmonary fibrosis model, chymase-positive and tryptase-positive mast cells accumulated in fibrotic lung. Lung tissue was decellularised and reseeded with bone marrow or peritoneum-derived mast cells; cells on fibrotic ECM released more TGF-β1 compared with normal ECM (active TGF-β1: bone marrow-derived mast cell (BMMC)-DL vs BMMC-TGF-β1 p=0.0005, peritoneal mast cell (PMC)-DL vs PMC-TGF-β1 p=0.0003, total TGF-β1: BMMC-DL vs BMMC-TGF-β1 p=0.013, PMC-DL vs PMC-TGF-β1 p=0.001). Mechanical stretch of lungs caused mast cell degranulation; mast cell stabilisers inhibited degranulation (histamine: cont vs doxantrazole p=0.004, β-hexosaminidase: cont vs doxantrazole, mean difference=1.007, 95% CI of difference 0.2700 to 1.744, p=0.007) and TGF-β1 activation (pSmad2/Smad2: cont vs dox p=0.006). Cromoglycate attenuated pulmonary fibrosis in rats (collagen: phosphate-buffered saline (PBS) vs cromoglycate p=0.036, fibrotic area: PBS vs cromoglycate p=0.031).ConclusionThis study suggests that mast cells may contribute to the progression of pulmonary fibrosis.
