Mapping the immune cell microenvironment by digital spatial profiling in muscle tissue injected with the venom of Daboia russelii

Project description:Pathological and inflammatory events in muscle after injection of snake venoms vary in different regions of the affected tissue and at different time intervals. In order to study such heterogeneity in the immune cell microenvironment, a murine model of muscle necrosis based on the injection of the venom of Daboia russelii was used.

The Arabian cousin: Comparative venomics of Daboia palaestinae and Daboia russelii

Project description:In this study, to unravel the influence of phylogenetic divergence and biogeography in shaping the composition and activity of Daboia venoms, we comparatively investigated the venoms of D. russelii from western India and D. palaestinae from Israel.

Proteomic analysis of Daboia russelli venom samples from Burdwan and Nadia districts of West Bengal, eastern India

Project description:Russell’s viper (Daboia russelii) (RV), a category I medically important snake as well as a member of the “Big Four”, is responsible for a heavy toll of snake bite mortality and morbidity in Indian sub-continent. Epidemiological studies suggest highest incidence of RV envenomation in eastern India (EI). In this study the RV venom proteomes from Burdwan and Nadia, the two districts of West Bengal, eastern India was deciphered for the first time using tandem mass spectrometry analysis.

A complex pattern of gene expression in tissue affected by viperid snake envenoming: the emerging role of autophagy-related genes

Project description:Cellular and inflammatory events were evaluated in mouse muscle after snake venoms Daboia russelii and Bothrops asper injection over time. A murine model of muscle necrosis based on venom injection was used to investigate up to 800 genes involved in fibrosis diseases and tissue regeneration using the multiplex RNA panel Fibrosis V2 from NanoString technology.

Longitudinal metabolomics and lipidomics analyses reveal markers of envenoming by Bothrops asper and Daboia russelii in an experimental murine model

Project description:Longitudinal metabolomics and lipidomics analysis was carried out in the blood plasma of mice injected intramuscularly with venoms of the viperid species Bothrops asper and Daboia russelii. Blood samples were collected 1, 3, 6 and 24 h after venom injection, and a control group of non-envenomed mice was included. Significant perturbations in metabolomics and lipidomics were observed at 1, 3 and 6 h, while values returned close to those of control mice by 24 h, hence reflecting a transient pattern of metabolic disturbance. Both venoms induced significant changes in amino acids, as well as in several purines and pyrimidines, and in some metabolites of the tricarboxylic acid cycle. KEGG analysis identified metabolic pathways that showed the highest changes, i.e., aminoacyl tRNA synthesis and amino acid biosynthesis and metabolism pathways. Regarding lipid metabolism, there was an increase of triglycerides and some acyl carnitines, concomitantly with a drop in the levels of some phospholipids. In addition, envenomed mice had higher levels of cortisol, heme and some oxidative stress markers. The overall pattern of metabolic changes in envenomed mice bears similarities with the patterns described in several traumatic injuries, thus underscoring a metabolic response/adaptation to the injurious action of the venoms.

Mapping the Immune Cell Microenvironment with Spatial Profiling in Muscle Tissue Injected with the Venom of Daboia russelii.

Project description:Pathological and inflammatory events in muscle after the injection of snake venoms vary in different regions of the affected tissue and at different time intervals. In order to study such heterogeneity in the immune cell microenvironment, a murine model of muscle necrosis based on the injection of the venom of Daboia russelii was used. Histological and immunohistochemical methods were utilized to identify areas in muscle tissue with a different extent of muscle cell damage, based on the presence of hypercontracted muscle cells, a landmark of necrosis, and on the immunostaining for desmin. A gradient of inflammatory cells (neutrophils and macrophages) was observed from heavily necrotic areas to less damaged and non-necrotic areas. GeoMx® Digital Spatial Profiler (NanoString, Seattle, WA, USA) was used for assessing the presence of markers of various immune cells by comparing high-desmin (nondamaged) and low-desmin (damaged) regions of muscle. Markers of monocytes, macrophages, M2 macrophages, dendritic cells, neutrophils, leukocyte adhesion and migration markers, and hematopoietic precursor cells showed higher levels in low-desmin regions, especially in samples collected 24 hr after venom injection, whereas several markers of lymphocytes did not. Moreover, apoptosis (BAD) and extracellular matrix (fibronectin) markers were also increased in low-desmin regions. Our findings reveal a hitherto-unknown picture of immune cell microheterogeneity in venom-injected muscle which greatly depends on the extent of muscle cell damage and the time lapse after venom injection.
