The Kwarteng laboratory is dedicated to research into tropical infections and non-communicable diseases. Our lab takes special interest in neglected diseases to explore the host immune responses and molecular mechanisms underlying these diseases of poverty in rural Ghana. In addition, our lab is also advancing research studies using an interdisciplinary approach and a cultural perspective, to fight social stigmatization and depressive mental illness in LF endemic communities in Ghana.
Of note, we seek to exploit the various microbial populations/communities and their role towards the progression and/or improvement among individuals with neglected tropical diseases, i.e. lymphatic filariasis, onchocerciasis (NTD-microbiome axis).
The Kwarteng lab with other collaborators is investigating the healing markers (MMP-9, MMP-2, TIMP-1, TGF-β, Galectins and NGAL) associated with the delayed wound healing of lymphatic filariasis individuals presenting with chronic wounds using the state-art-facilities at KCCR. Furthermore, we aim to investigate the relationship of these markers with the wound healing process as well as the general immune profile (Th1, Th2, Th17 and T regs) of the LF patients.
We are also using several bioinformatics pipelines and computational biology techniques to understand the mechanisms underlying these diseases; identify specific biomarkers and potential vaccine candidates. Here, we use techniques ranging from epitope-prediction, immune simulation, drug discovery, transcriptomics and protein structure analysis. Furthermore, we also spend our energies to explore novel pathways of non-communicable diseases such as breast cancer, hepatitis etc. using single cell RNA and DNA sequencing approaches.
The Kwarteng Lab has investigated the possible complications of secondary bacterial infection among the individuals presenting with filarial lymphedema which was known as the SecBile Project and was hosted at KCCR

Title: Impact of secondary bacterial infection in the development of filarial lymphedema among Ghanaian patients (SECBILE)
Filarial infections are among the most important diseases in sub-Saharan Africa and are strongly associated with poverty. Bacteria and fungi are believed to be important opportunists among individuals living with lymphedema following a break in the skin’s integrity. However, this remains to be documented among individuals with lymphedema in Ghana, where about 20% develop this form of pathology in LF endemic regions. Therefore, this study seeks to address the current knowledge gap by investigating secondary bacterial and fungi populations that are implicated in the development of LE in Ghana. Taken together, these would inform practice with regards to the common secondary microbial populations that could be targeted during the course of LE management in Ghana as well as setting the foundations for the development of novel immunotherapeutic needed for treatment and management of LF.
Project Tile: Investigating mental health and disease-related stress among lymphatic filariasis patients in Ghana (LF-STRESS)
There is growing evidence that neglected tropical diseases predispose individuals to poor mental health given the high stigma and discrimination associated with these diseases. However, it is also estimated that mental health will be the greatest contributor of global health burden by 2030, while the link between lymphatic filariasis and its physiological and psychological impacts remains to be fully established with research evidence. Therefore, this study investigates the psychological and emotional impact of lymphatic filariasis in LF-endemic communities such as Ghana.
Project Title: The frequency of filarial attacks among lymphedema patients: A focus on leg stage, adherence to foot-care hygiene, and the impact of seasonal variations (LF-ATTACK)
Our understanding of the disease (lymphedema) dynamics and the impact of environmental factors on the progression of lymphedema is limited. Therefore, knowledge of the seasonal variations on filarial attacks among lymphedema patients will be key in the development of appropriate interventions for effective management of these attacks. We anticipate that this study will shed lights on the dynamics of LF attacks among lymphedema patients. Through this study, our understanding of the impact of environmental factors (weather) on lymphedema disease progression will be expanded thereby serving as the basis for the development of new management practices or revising existing ones where necessary.
Project Title: Microbial pathogens contributing to non-healing wounds among lymphatic filariasis patients in Ghana (LF-BAC)
Identifying the factors that promote non-healing wounds is crucial in developing novel therapeutics that will eventually make individuals with filarial diseases productive. This project seeks to characterize and compare the microbial populations from wounds of filariasis patients and non-filarial patient’s wounds; to determine the antimicrobial susceptibility of isolated microbial populations; to determine the differential host immune response among patients with advanced filarial wounds and non-filarial patient’s wounds in filarial endemic communities in Ghana.
