Write-up of research and development interests/focus, past and present goals:

The primary interest of my research group is to develop animal models of various disease conditions and to study the therapeutic efficacy of test compounds against these models. During the last few years, we have been studying the therapeutic role of plasma gelsolin (pGSN) in different diseases. Several reports in literature suggest that exogenous administration of GSN leads to improvement of condition in sepsis and burn in various rodent models advocating the need for “gelsolin replacement therapy”. 

I. Analgesic and anti-inflammatory properties of gelsolin in acetic acid-induced writhing, tail immersion and carrageenan-induced paw edema in mice

This study was planned to examine the analgesic and anti-inflammatory activity of exogenous gelsolin in mice models of pain and acute inflammation. Administration of gelsolin not only demonstrated a significant reduction in the number of acetic acid-induced writhing effects but also exhibited analgesic property intail immersion test in mice as compared to placebo-treated mice. Additionally, the anti-inflammatory function of gelsolin was confirmed in the carrageenan induced paw edema where the inflammation was measured by vernier caliper and fluorescent tomography imaging. Interestingly, carrageenan groups pretreated with gelsolin or the anti-inflammatory drug diclofenac sodium showed a marked decrease in edema and infiltration of inflammatory cells in paw tissue. Analysis of cytokines and histo-pathological examinations of tissue revealed that administration of gelsolin and diclofenac sodium significantly reduced production of pro-inflammatory cytokines, TNF-α and IL-6.

II. Role of gelsolin and its truncated versions in improving type II diabetes in mice 

In this study we reported for the first time that pGSN values decline in type II diabetic humans and mice models. Administration of recombinant pGSN and its truncated forms could decrease blood sugar levels in diabetic mice as tested by oral glucose tolerance test when treated daily for one week. Results of this study propose that gelsolin level monitoring and replacement of F-actin severing capable gelsolin(s) should be considered in the management of diabetes.

III. Therapeutic role of thrombolytic proteins in thrombosis / stroke models of mice and rats

This ongoing project is part of IMTECH’s BIODISCOVERY project in collaboration with Dr. Girish Sahni, DG, CSIR (for testing streptokinase and its derivatives in animals) and with Dr. Ashish (for testing efficacy of gelsolin). In CSIR-IMTECH, Dr. Sahni has done extensive research for the discovery of new and improved versions of thrombolytic drugs (Streptokinase and its mutants) leading to development of novel clot busters with clot specific and anti-thrombotic properties. 

Gelsolin levels have been reported to decrease in many diseases and exogenous administration leads to improvement of conditions in rodent models of sepsis, burn, diabetes, acute inflammation etc. It is also showing anti-thrombotic activities in preliminary animal experimentations done by us in IMTECH. 

Objectives of the projects: 

Standardization and characterization of  animal models of thrombosis and middle cerebral artery occlusion (MCAO) model of stroke and Insight into the molecular mechanism and patho-physiology of stroke using state of the art animal  MRI

Evaluation of the efficacy of thrombolytic drugs developed in IMTECH (new derivatives of SK / tPA / gelsolin) to study the thrombolytic effect of new improved bio-generics of streptokinase / tPA / gelsolin
