Granulomatous disorders include a wide variety of infectious and non-infectious conditions with heterogeneous clinical courses considerable constraints affected organs. We take cutaneous sarcoidosis as model disease to acquire new insights into the pathomechanisms granulomas. combined single-cell high-dimensional spatial transcriptomics fluorescently labeled antibody detection for protein expre...

BACKGROUND Sarcoidosis is a granulomatous disease characterized by a seemingly exaggerated immune response against a difficult to discern antigen. Dendritic cells (DCs) are pivotal antigen presenting cells thought to play an important role in the pathogenesis. Paradoxically, decreased DC immune reactivity was reported in blood samples from pulmonary sarcoidosis patients. However, functional dat...

Murine schistosomiasis is a granulomatous disease associated with high serum and granuloma angiotensin I-converting enzyme (ACE) activity. SQ 14225, a specific competitive inhibitor of ACE, was administered to normal mice and mice infected with Schistosoma mansoni to determine whether this compound could inhibit granuloma ACE activity and modify the size of the granulomatous response to schisto...

OBJECTIVE The roots of Chlorophytum borivilanum are used in traditional medicine for the treatment of arthritis and inflammation. The aim of the work was to evaluate the anti-inflammatory activity of isolated saponins from Chlorophytum borivilianum (ISCB). METHODS The ISCB was screened using the carrageenan-induced paw edema, histamine-induced paw edema, cotton pellet-induced granuloma, and F...

The aim of this study was to analyze the chemical composition and investigate the anti-inflammatory property of the supercritical-carbon dioxide extract from flowers and buds of C. indicum (CISCFE). The anti-inflammatory effect was evaluated in four animal models including xylene-induced mouse ear edema, acetic acid-induced mouse vascular permeability, carrageenan-induced mouse hind paw edema, ...

Schistosoma mansoni egg-induced pulmonary granuloma formation is a cell-mediated inflammatory response associated with dominant Th2-type cytokine expression, tissue eosinophilia, and high levels of serum IgE. In the present study, we show that in vivo blockade of the Th2 cytokine IL-13, using soluble IL-13R alpha2-Fc fusion protein, significantly reduced the size of pulmonary granulomas in unse...

Early-stage hepatic granuloma and advanced-stage fibrosis are important characteristics of schistosomiasis. The direct consequences of gadolinium chloride (GdCl3) in egg-induced granuloma formation have not been reported, although GdCl3 is known to block the macrophages. In present study, mice were infected with 15 Schistosoma japonicum (S. japonicum) cercariae and treated with GdCl3 (10 mg/kg ...

Bacille Calmette Guérin (BCG)-induced granulomas contain T cells that express a broad TCR repertoire even at the level of the individual lesion. We have developed a BCG infection model in mice having only one T cell specific for a recombinant BCG epitope expressed in a lipoprotein fusion protein. Here we report that the single T cell model induces well-formed granulomas, but has weaker protecti...

An experimental model to investigate orbital granuloma formation in inbred rats was established. Animals sensitized to trinitrophenyl ovalbumin (TNP-OA) and challenged retro-orbitally with TNP-OA covalently linked o Sepharose 4B beads specifically developed a granulomatous response. This granulomatous reactivity was passively transferred into normal animals by lymph node cells, but not by serum...

The new ex vivo model system measuring functional input of individual granuloma cells to formation of granulomatous inflammatory lesions in mice with latent tuberculous infection has been developed and described in the current study. Monolayer cultures of cells that migrated from individual granulomas were established in the proposed culture settings for mouse spleen and lung granulomas induced...
