We examined the expression of interleukin-1 alpha (IL-1 alpha), IL-1 beta, IL-2, IL-3, IL-4 and granulocyte/macrophage colony-stimulating factor (GM-CSF) at the mRNA level in fresh leukemic cells from 20 adult T cell leukemia patients to see whether there is any association between cytokine expression and HTLV-I expression and between their expression and clinical manifestations such as hypercalcemia or neutrophilia.

Freshly isolated leukemic cells from patients with adult T-cell leukemia (ATL) produce high levels of interleukin-1 (IL-1), which is believed to play an important role in neutrophilia, elevation of C-reactive protein, osteolytic bone lesions, hypercalcemia, and fever in ATL.

We reported first in this study that human thyroid cell line NIM 1 established from a patient with papillary adenocarcinoma of the thyroid associated with hypercalcemia and peripheral neutrocytosis produced interleukin (IL)-1 alpha and IL-1 beta in the culture supernatant and cell lysate as detected by murine thymocyte proliferative response and enzyme-linked immunosorbent assay.
TNFR:Fc strongly inhibited endothelial cell activation (plasma levels of soluble E-selectin), modestly reduced neutrophil responses (neutrophilia and plasma concentrations of elastase-alpha1-antitrypsin complexes and lactoferrin), but did not affect the release of secretory phospholipase A2 or lipopolysaccharide-binding protein (P > .05).
However, this technique can be complicated by excessive lyonization of normal cells mimicking clonal cell growth: We analyzed XCI patterns at the human androgen receptor (HUMARA) locus in 146 healthy females, 65 women with secondary neutrophilia, 31 women with reactive thrombocytosis, and 86 women with chronic MPDs.
Factors other than overproduction of G-CSF and extensive neutrophilia could be required for the development of neutrophil-mediated acute and chronic tissue damage.
In conclusion, the data suggest that the coincidence of neutrophilia and upregulation of transforming growth factor-beta1 in obliterative bronchiolitis may lead to uninhibited neutrophil elastase activity by downregulation of secretory leukoprotease inhibitor, with the consequence of ongoing injury to the epithelium.

Increased levels of interleukin (IL)-5 and eosinophil cationic protein, but equal levels of eotaxin, were found in effluent from the PFE patients compared to the patient with neutrophilia.

In addition, IL-17E induces G-CSF production in vitro and mIL-17E-transgenic mice had increased serum G-CSF and exhibit neutrophilia, a property shared by IL-17.
Intranasal administration of adenovirus expressing IL-17, IL-17C, or IL-17F resulted in bronchoalveolar lavage neutrophilia and inflammatory gene expression in the lung.
KARAP/DAP12-transgenic mice present, in a transgene dose-dependent manner, a complex phenotype characterized by two independent and spontaneous hematological abnormalities: (i) a severe lymphopenia and (ii) a massive inflammatory syndrome associated with neutrophilia and lung infiltration by multinucleated macrophages.
Immunophenotypically, the neoplastic cells were positive for CD30, CD4, leukocyte common antigen, anaplastic lymphoma kinase-1, epithelial membrane antigen, and granzyme B.She had no peripheral neutrophilia.
Interleukin-8 gene expression and protein release were increased in allergic bronchopulmonary aspergillosis and correlated with airway neutrophilia and airway obstruction.
Thus, in COPD, in addition to CXCL8 and CXCR1, CXCL5 and CXCR2 appear to play important roles in the airway neutrophilia characteristic of severe exacerbations.
