Research Interests
My research program centers on understanding the molecular and cellular mechanisms driving therapeutic resistance in acute myeloid leukemia (AML), with a particular focus on FLT3-ITD–mutant AML, leukemia stem cells (LSCs), and the bone marrow microenvironment. I am deeply interested in how metabolic adaptations and hypoxic signaling within the bone marrow niche foster leukemic persistence and resistance to targeted therapies, and in leveraging this knowledge to develop novel therapeutic strategies.
A major line of my work investigates hypoxia-driven resistance to FLT3 inhibitors. Although FLT3 inhibitors such as gilteritinib and quizartinib improve outcomes, patients frequently relapse, with blasts persisting in the hypoxic bone marrow. In parallel, I am committed to building preclinical models that faithfully recapitulate the patient microenvironment and also contribute to the advancement of New Alternative Methods (NAMs), reducing reliance on animal testing.
Beyond AML, and an intensive training in Chronic Myeloid Leukemia RNA and stem biology, my research background spans immunology, virology and bacteriology, with prior work in influenza, COVID-19 and mycoplasma immunopathogenesis. This foundation in viral-host interactions informs my current exploration of stress-adaptive responses in cancer, as both contexts demand understanding how cells survive under hostile microenvironments.
Ultimately, my long-term research goal is to translate mechanistic insights into therapeutic innovation. By dissecting the metabolic and microenvironmental regulation of FLT3-ITD and LSCs, and by advancing platforms for drug discovery, I aim to develop strategies that improve survival and reduce relapse in AML patients.

“From the historic center of Rende to the United States to fight on the front line against the Coronavirus. Giovannino Silvestri from Rende is also part of the team of scientists who have proposed a new therapeutic protocol for the treatment of Covid-19 to the Annunziata hospital in Cosenza.
Raised in the ancient village of Oltre Campagnano, he has lived in the USA since 2013 and works as an associate researcher at the Institute of Human Virology of the University of Maryland in Baltimore. Born in 1984, he graduated with honors from the Faculty of Biology of the University of Calabria in 2009 and three years later obtained his PhD from the University of Verona in biology and molecular and cellular pathology.
In recent weeks his research work has focused on the Covid-19 pandemic which is unfortunately claiming thousands of victims all over the world. "To date, there is no known effective pharmacological treatment for which therapeutic alternatives are needed to alleviate and stop this pandemic due to a completely new virus," explains Silvestri. «The work of which I co-authored with Ennio Avolio, Teresa Pasqua and Giuseppe Palma, involves the use of the treatment of two drugs capable of acting together and mitigating the worsening of the lung disease, the now sadly famous syncytial pneumonia, caused by Sars-Cov-2 ”, underlines the researcher. «The treatment consists of a selective antagonist of peripheral H1 histaminergic receptors in combination with a specific inhibitor of one of the inflammatory cascades which, when activated, causes a strong perturbation of the immune responses with a typical pulmonary clinical picture of Covid-19», he highlights."This new therapeutic protocol - concludes Silvestri - could give an important turning point in the treatment of Covid-19 patients, especially in the early stages of the evolution of the pathology, that is, in avoiding or reducing the need for treatment in intensive care". https://www.quotidianodelsud.it/calabria/lintervista/salute-e-assistenza/2020/04/03/coronavirus-la-terapia-antivirus-dal-ricercatore-calabrese-negli-usa April 2022, Italy. - Chronic myelogenous leukemia (CML) is a stem cell disorder once considered an eventual death sentence upon progression to the terminal acute/blastic cell phase, a terrible clinical outcome that has improved with the introduction of tyrosine kinase inhibitors. A major continuing problem with treating CML is the persistence of drug-resistant leukemia stem/initiating cells (LS/IC).In the first issue of Blood Cancer Discovery, Silvestri and colleagues describe an incredibly in-depth mechanistic study using genetic and pharmacologic modulation of the miRNA MiR300 with and without treatment with activators of the serine-threonine protein phosphatase 2A (PP2A) in human cells. In vitro studies and in vivo mouse models of patient-derived xenografts were used to address the need to target LS/ICs and restore immunity of impaired natural killer cells for attenuation of CML progression.

«To Giovannino Silvestri a brilliant mind who, with his research, gives hope and faith in science». These were the words imprinted on the silver plaque given by the mayor Manna to the transplanted biologist in Baltimore where he has lived for 10 years and works as an associate researcher at the Institute of Human Virology at the University of Maryland. In addition to the doctor's parents, the Assessors Annamaria Artese, Lisa Sorrentino and Fabrizio Totera took part in the ceremony. «It is an honor to have this illustrious citizen who, with his work, offers the possibility of treatment for patients suffering from chronic myeloid leukemia» said Mayor Marcello Manna. Dr Silvestri, during the stop forced by the pandemic, helped also to activate a treatment at the Cosenza hospital that avoids the complications of the consequences of pneumonia: “Although I have lived in America for some time - said Silvestri - where I came to work with Robert Charles Gallo, US academic, discoverer of the retroviral origin of AIDS in 1982, I am very fond of my roots and this is where I trained and graduated. I thank my city for this important recognition”. https://www.ilpendolo.it/la-citta-di-rende-omaggia-il-concittadino-di-fama-mondiale-giovannino-silvestri/ October 2022, Italy.

A team of researchers from the University of Maryland School of Maryland’s (UMSOM) Institute of Human Virology (IHV), a Center of Excellence of the Global Virus Network (GVN), published new findings that emphasize the crucial role of the urinary and genital tract microbiota in adverse pregnancy outcomes and genomic instability that originate in the womb during fetal development.
The study, published on July 17 in the Proceedings of the National Academy of Sciences of the United States of America (PNAS), established a new link between genomic instability, reduced fertility, and a protein from Mycoplasma fermentans, a kind of bacterium that commonly colonizes the urogenital tract in humans.
This research was spearheaded by Davide Zella, PhD,Assistant Professor of Biochemistry and Molecular Biology at UMSOM’s IHV and Robert Gallo, MD, The Homer & Martha Gudelsky Distinguished Professor in Medicine, Co-Founder and Emeritus Director of UMSOM’s IHV, and Co-Founder and Chair of the Scientific Leadership Board of the Global Virus Network.
"Our results not only broaden our understanding of the interplay between the urogenital tract microbiota and human reproductive health, but also shed light on the previously unidentified contribution of the human microbiota to genetic abnormalities," said co-lead author on the study Francesca Benedetti, PhD, Research Associate of Biochemistry and Molecular Biology in UMSOM’s IHV.
“We aim to further explore the mechanisms underlying these findings and their potential implications for preventing and treating chromosomal abnormalities and genetic diseases,” said co-lead author Giovannino Silvestri, PhD, former Research Associate of Medicine in UMSOM’s IHV.
The human microbiota is known to affect metabolism, susceptibility to infectious diseases, immune system regulation, and more. One of these bacterial components, Mycoplasmas, have been linked to various cancers.
The research team has been studying one Mycoplasma protein, DnaK, which belongs to a family of proteins that safeguards other bacterial proteins against damage and aids in their folding when they are newly made, acting as a so-called ‘chaperone.’ However, while this protein is advantageous for bacteria, its effects on animal cells are less favorable. To this regard, the team had previously demonstrated that this DnaK is taken up by the body’s cells and it interferes with key proteins involved in preserving DNA integrity and in cancer prevention, such as the tumor suppressor protein p53.
