Abstract
The progressive worsening of disc degeneration and related nonspecific back pain are prominent clinical issues that cause a tremendous economic burden. Activation of reactive oxygen species (ROS) related inflammation is a primary pathophysiologic change in degenerative disc lesions. This pathological state is associated with M1 macrophages, apoptosis of nucleus pulposus cells (NPC), and the ingrowth of pain-related sensory nerves. To address the pathological issues of disc degeneration and discogenic pain, we developed MnO2@TMNP, a nanomaterial that encapsulated MnO2 nanoparticles with a TrkA-overexpressed macrophage cell membrane (TMNP). Consequently, this engineered nanomaterial showed high efficiency in binding various inflammatory factors and nerve growth factors, which inhibited inflammation-induced NPC apoptosis, matrix degradation, and nerve ingrowth. Furthermore, the macrophage cell membrane provided specific targeting to macrophages for the delivery of MnO2 nanoparticles. MnO2 nanoparticles in macrophages effectively scavenged intracellular ROS and prevented M1 polarization. Supportively, we found that MnO2@TMNP prevented disc inflammation and promoted matrix regeneration, leading to downregulated disc degenerative grades in the rat injured disc model. Both mechanical and thermal hyperalgesia were alleviated by MnO2@TMNP, which was attributed to the reduced calcitonin gene-related peptide (CGRP) and substance P expression in the dorsal root ganglion and the downregulated Glial Fibrillary Acidic Protein (GFAP) and Fos Proto-Oncogene (c-FOS) signaling in the spinal cord. We confirmed that the MnO2@TMNP nanomaterial alleviated the inflammatory immune microenvironment of intervertebral discs and the progression of disc degeneration, resulting in relieved discogenic pain.

Abstract
Investigations sought to discover the biochemical mechanisms in macrophages that mediate the `shedding' of soluble CD14 fragment. Stimulated macrophages display both increased liberation of soluble CD14 fragment and decreases in residual membrane-associated CD14 complexes following exposure to activating agents ( fMLP/A23187). Application of `class-specific' protease inhibitors revealed that a thiol/cysteine was involved in the biochemical production of soluble CD14 fractions and that a metalloprotease enzymatically degraded soluble CD14 fragment. Exposure of macrophages to individual proteases revealed that both cathepsin-D and elastase promoted variable depletion of membrane-associated CD14 complexes. Additionally, cathepsin-D, and to a lesser extent elastase, generated soluble CD14 fragment. Related studies isolated a carboxyl/aspartate protease from activated macrophages using pepstatin-A affinity chromatography. The physical and functional properties of macrophage pepstatin-A binding protein fractions closely corresponded with the known characteristics of cathepsin-D with respect to: (i) cellular origin; (ii) binding-avidity of carboxyl/aspartate proteases for pepstatin-A; (iii) non-specific proteolysis of haemoglobin detected by Hb-PAGE zymography; and (iv) hydrolysis of a synthetic cathepsin-D-specific peptide substrate. Interpretation of these findings collectively implies that activated leukocytes can biochemically alter membrane-associated CD14 complex expression and promote the liberation of soluble CD14 fragment in both activated and non-activated cell populations.

Abstract
We measured levels of pro-inflammatory cytokines in the cerebrospinal fluid (CSF) of patients with mumps meningitis, enteroviral echovirus 30 meningitis and children without central nervous system infection to investigate whether these molecules were involved in the pathogenesis of viral meningitis. The CSF was obtained from 62 children suspected with meningitis. These patients were classified to the mumps meningitis (n = 19), echovirus 30 meningitis (n = 22) and non-meningitis (n = 21) groups. The concentrations of interleukin-1 (IL-1), interleukin-1 soluble receptor type 2 (IL-1R2), interleukin-8 (IL-8), human interferon gamma (IFN-γ) and human tumour necrosis factor alpha (TNF-α) were determined by immunoassay. A significant increase was noted in the levels of IL-8, TNF-α and IL-1R2 in the CSF of both meningitis groups as compared to controls. The concentrations of IFN-γ and IL-1 differed significantly only between the mumps group and control. The levels of IL-1, IFN-γ and TNF-α were significantly higher in mumps meningitis when compared to the echovirus 30 group. Of all cytokines examined, only IFN-γ correlated with pleocytosis (r = 0.58) in the mumps meningitis group. The increased CSF cytokine levels are markers of meningeal inflammation, and each virus may cause a specific profile of the cytokine pattern.

Abstract
BACKGROUND AND OBJECTIVES Cathepsin D is an aspartyl proteinase involved in tumoral invasion. The aim of this work was to study cathepsin D cytosolic levels in squamous carcinomas of the lung and their correlation with several clinical and biological parameters. PATIENTS AND METHOD The study group included 95 squamous lung carcinomas and 38 normal tissue samples from the same patients. Cathepsin D cytosolic concentrations were determined using an immunoradiometric assay (CIS BioInternational. France). EGFR, erbB2 protein, CD44s, CD44v5 and CD44v6 levels at cell surfaces were determined. The clinical stage, histological grade, ploidy and S-phase cellular fraction (SP) were also considered as variables of the study. RESULTS Cathepsin D cytosolic levels oscillated between 7.7 and 576 (median: 38.8) pmol/mg protein and were lower (p = 0.001) than those observed in 38 normal lung samples from the same patients. When tumors were classified according to different clinical and biological parameters, we noticed that cathepsin D levels were higher in carcinomas with lower proliferation rates and no nodal involvement, reaching statistical significance in both cases. Moreover, when lung carcinomas were classified according to cathepsin D concentrations, tumors with higher cathepsin D concentrations had lower EGFR levels (p = 0.011) and small global SP values (p = 0.025) and DNA index (p = 0.023). Likewise, they were found to be CD44s positive more frequently (p = 0.001) and SP positive less frequently (p = 0.022). CONCLUSIONS These results lead us to suggest the following: a) in squamous carcinomas of the lung, cathepsin D cytosolic levels are lower than those observed in normal lung samples from the same patients, and b) in this subtype of lung carcinomas, high cathepsin D levels are associated with tumors without nodal involvement, with low proliferation rates, lower EGFR levels, and a reduced positivity for CD44s, pointing to a possible role of this proteinase as a parameter of good outcome.

Abstract
The research aim of the present investigation was to identify leukocyte enzyme-proteases that have the capacity to biochemically recruit the passive participation of vascular endothelium in cytokine receptor 'shedding' phenomenon involving membrane-associated TNF RII (80-kDa) and IL-1 RI (80-kDa) complexes. Achieving this research objective involved the design of a laboratory approach that delineated to what extent enzyme-proteases released by activated macrophages directly interact with, and liberate soluble fragments of membrane-associated cytokine receptor complexes. Results from this segment of the investigation revealed that cathepsin-D, a leukocyte carboxyl/aspartate protease, altered the integrity and generated soluble fragments of TNF RII (80-kDa) and IL-1 RI (80-kDa) receptor complexes expressed by vascular endothelium. Furthermore, laboratory findings also suggested that cathepsin-D possessed the ability to variably deplete biologically functional membrane-associated TNF RII (80-kDa) and IL-1 RI (80-kDa) complexes. Complementary investigations isolated a carboxyl/aspartate protease from activated macrophages utilizing pepstatin-A affinity chromatography. Exposure of vascular endothelium to pepstatin-A binding proteins resulted in a detectable depletion of membrane-associated TNF RII (80-kDa) and IL-1 RI (80-kDa) in addition to the generation of soluble receptor fragments. Analysis of macrophage pepstatin-A binding proteins by SDS-PAGE identified a primary fraction with a molecular mass of 47-52-kDa that closely correlated with the known molecular mass of leukocyte cathepsin-D. Evaluation of macrophage pepstatin-A binding-protein fractions by non-denaturing Hb-PAGE detected a lucent proteolytic band at 47-52-kDa compatible with the known molecular mass of leukocyte cathepsin-D. Macrophage pepstatin-A binding proteins also hydrolyzed a synthetic enzyme-specific substrate that selectively recognizes cathepsin-D biochemical activity. In conclusion, the leukocyte carboxyl/aspartate protease, cathepsin-D can biochemically alter the integrity and generate soluble fragments of membrane-associated TNF RII (80-kDa) and IL-1 RI (80-kDa) receptor complexes expressed by vascular endothelium. The relevance of this concept is in part based on investigations that have discovered that genetic 'knock-out' mice incapable of expressing IL-1 RI (80-kDa) or TNF RI (55-kDa) receptor complexes are highly resistant to developing the pathophysiological alterations classically associated with conditions of endotoxic-shock.
