Trehalose 6,6'-dimycolate (TDM), a cord factor of Mycobacterium tuberculosis (Mtb), is an important regulator of immune responses during Mtb infections. Macrophages recognize TDM through the Mincle receptor and initiate TDM-induced inflammatory responses, leading to lung granuloma formation. Although various immune cells are recruited to lung granulomas, the roles of other immune cells, especia...

Mallotus philippensis L.(MP) commonly known as Kamala tree in Hindi,is a small to medium-sized monoecious tree.The objective of the study was to evaluate the anti-inflammatory activity of MPand a new flavanoneisolated from it by using in vivo models of inflammation.Albino wistar rats of either sex weighing 150-200g were used. Seven groups were made (n = 6), namely normal control group (normal s...

OBJECTIVE In this study, we evaluated anti-inflammatory activity of leaves of Fumaria parviflora (F. parviflora) and underlying mechanisms by using in vivo models of inflammation. MATERIAL AND METHODS Albino Wistar rats of either sex weighing 150 - 200 g were used. Soxhlet ethanol and aqueous extracts of leaves of F. parviflora (EFP and AFP) were prepared. The anti-inflammatory activity was s...

Objectives-To evaluate anti-inflammatory activity of rosiglitazone in the acute and chronic models of inflammation. Also to determine ulcerogenic potential on gastric mucosa in Wistar rats in comparison with diclofenac. Methodology-Anti-inflammatory effects of rosiglitazone in the dose of 1, 3 and 10 mg/kg b.wt., i.p were studied in acetic acid-induced peritoneal capillary permeability model in...

some lesions in the oral cavity and mostly on gingiva have predominant predilection towards females, and mostly occur in the first four decades of life when changes in sex hormone levels in blood are obvious. the present study aimed to investigate the presence and distribution of estrogen and progesterone receptors in peripheral giant cell granuloma (pgcg), pyogenic granuloma (pg) and periphera...

Interleukin (IL)-33 is involved in T helper (Th)2-biased immune responses in mice infected with Schistosoma, but the precise mechanism remains to be elucidated. Herein, we investigated the role of IL-33 and its receptor ST2L in hepatic granuloma pathology induced by Schistosoma japonicum infection. We found that IL-33 induced the increased production of IL-5 and IL-13 from splenocytes and liver...

In the present study, anti-anaphylactic, anti-inflammatory and membrane stabilizing properties of a lupine alkaloid plumerianine (compound 1), isolated from the root bark of Plumeria acutifolia Poir were investigated in animal models. The anti-anaphylactic activity of compound 1 (10, 25 and 50 mg/Kg) was studied by using models such as passive cutaneous anaphylaxis, passive paw anaphylaxis and ...

BACKGROUND Ardisia crispa (Myrsinaceae) is used in traditional Malay medicine to treat various ailments associated with inflammation, including rheumatism. The plant's hexane fraction was previously shown to inhibit several diseases associated with inflammation. As there is a strong correlation between inflammation and angiogenesis, we conducted the present study to investigate the anti-angioge...

Tuberculosis is characterized by granuloma formation and caseous necrosis, but the factors causing tissue destruction are poorly understood. Matrix metalloproteinase (MMP)-9 (92-kDa gelatinase) secretion from monocytes is stimulated by Mycobacterium tuberculosis (M. tb) and associated with local tissue injury in tuberculosis patients. We demonstrate strong immunohistochemical MMP-9 staining in ...

Granulomas are aggregates of immune cells that can form in various organs. In cutaneous sarcoidosis macrophages and T present inside granuloma cores not able to eliminate the yet unknown antigen arrest an state causing tissue destruction. We aim study switch a protective cell phenotype pathological, disease-driving population within granulomas. Therefore, we use combination direct visualization...
