Briefly describe the following paragraph
A wealth of literature has highlighted the discovery of various immune modulators, frequently used in clinical practice, yet associated with numerous drawbacks. In light of this pharmacological deficiency, medical scientists are motivated to develop new immune modulators with minimized adverse effects yet retaining the improved therapeutic potential. T-cell differentiation and growth is central to human defense and is regulated by interleukin-2 (IL-2), an immune-modulatory cytokine. However, the scientific investigation is mired due to its flat binding site and widespread hotspot residues. In this regard, prompt and logical investigation guided by integrated computational techniques was undertaken to unravel new  and potential leads against IL-2. In particular, the combination of score-based and pharmacophore-based virtual screening approaches were employed, reducing the data from millions of small molecules to manageable number. Subsequent docking and 3D-QSAR prediction via CoMFA further helped to remove false positives from data. The extensive virtual screening herein leads to the identification of a total of 24 leads with potential anti-IL-2 activity. Further, the theoretical findings were in corroboration with In-vitro testing further endorsing the anti-inflammatory potential of the identified leads.
