Studies On The Leukocyte-Associated Ig-Like Inhibitory Receptor-1 Signaling Pathway In T Lymphocytes, Chidi Zacheaus
Studies On The Leukocyte-Associated Ig-Like Inhibitory Receptor-1 Signaling Pathway In T Lymphocytes, Chidi Zacheaus

Inflammation is a natural process in which the immune system concertedly responds to pathogens and abnormal cell growth to protect the host. For an efficient/effective immune response that circumvents tissue atrophy, a delicate balance between stimulatory and inhibitory mechanisms is essential for the proper functioning of the immune system. Immuno-receptor Tyrosine-based Inhibitory Motif (ITIM)-bearing receptors in immune cells, including T lymphocytes, play a major role in preventing autoimmune responses. Leukocyte-associated Ig-like Inhibitory Receptor 1 (LAIR-1) is one of ITIM-bearing receptors. The mechanism by which LAIR-1 attenuates T-cell response has yet to be completely understood. In this study, I investigated a …

Neuroblastomas (NB) are embryonal childhood tumors that derive from the multipotent neural crest cells (NCCs) of the peripheral nervous system. NB accounts for more than 15% of all childhood cancer-related deaths. Despite the most intensive multimodal therapy, more than 50% of patients with high-risk NB relapse with often fatal, resistant disease. Novel therapies are desperately needed to improve cure rates. Previous studies proposed that the deregulation of normal neural crest developmental programs contributes to NB oncogenesis by retaining the highly migratory and proliferative traits of NCCs. Thus, activation or repression of neural crest developmental pathways have been implicated in NB …

Following a traumatic brain injury, microglia become overactive for long periods and display pathologic behavior. We have shown that concentrated conditioned media from adipose tissue-derived mesenchymal stem cells (MSC-CCM) can suppress microglial activation. In this pilot study, we evaluated the efficacy of exosomes containing TNF-stimulated gene 6 (TSG6) derived from MSC-CCM on decreasing microglial activation in vitro via phagocytic activity and pro-inflammatory microglial gene expression.

Introduction. Ischemic heart disease (IHD) is a major concern of human health issue. The structural repair and functional recovery of injured hearts is a major challenge in the clinical setting. Preclinical studies over last 10 years have demonstrated the potential of using stem cells to treat IHD, but the efficacy of this therapy is jeopardized by uncontrollable migration and low survival of the injected stem cells. An approach based on tissue engineering enabling target-specific stem cell delivery such as cardiac patches has emerged as an alternative solution for stem cell therapy for IHD. It employs scaffold materials to engulf various …
Investigation Of Clinically Relevant Fluconazole Resistance Mechanisms In The Fungal Pathogen Candida Parapsilosis, Laura Anne Doorley
Investigation Of Clinically Relevant Fluconazole Resistance Mechanisms In The Fungal Pathogen Candida Parapsilosis, Laura Anne Doorley
Theses and Dissertations (ETD)
Invasive candidiasis is a severe fungal infection associated with significant morbidity and mortality, particularly among the critically ill and immunocompromised. Candida parapsilosis is the most common non-albicans species causing invasive Candida infections in pediatric and neonatal populations worldwide and is particularly common in the countries of South America, Western Asia, Mediterranean Europe, and Southern Africa. For many of these countries, fluconazole and other triazoles are the first line antifungal agents used for effective treatment of invasive Candida infection. Until recently, rates of fluconazole resistance among C. parapsilosis isolates were relatively low, therefore the determination of clinically relevant resistance mechanisms in …

Despite being an ancient disease caused by Mycobacterium tuberculosis (Mtb) and after decades of research, tuberculosis (TB) still affects millions of people every year worldwide. In 2018, the World Health Organization (WHO) reported that 10 million people developed tuberculosis and 1.5 million died of the disease. With the increase in the multidrug-resistant (MDR) and extensively drug-resistant (XDR) cases, the treatment for TB with the standard first and second-line therapy is becoming increasingly difficult. Therefore, there is an urgent need to find new anti-TB drugs as combination partners of existing and experimental classes of antimicrobial agents to shorten and simplify the …
