✦ Synopsis

The proposed book is envisioned for the nascent and entry-level researchers who are interested to work in the field of drug delivery and its applications specifically for macrophage targeting. Macrophages have gained substantial attention as therapeutic targets for drug delivery considering their major role in health and regulation of diseases. Macrophage-targeted therapeutics have now added significant value to the lives and quality of life of patients, without undue adverse effects in multiple disease settings. We anticipate examining and integrating the role of macrophages in the instigation and advancement of various diseases. The major focus of the book is on recent advancements in various targeting strategies using delivery systems or nanocarriers followed by application of these nanocarriers for the treatment of macrophage associated disorders.

Macrophage Targeted Delivery Systems is primarily targeted to Pharmaceutical Industry Academia, Medical Pharmaceutical Professionals, Undergraduate Post graduate students and Research Scholars, Ph.D, post docs working in the field of medical and pharmaceutical sciences.
