“…The lower fluctuation values of the bound vaccines and vaccine complexes compared to the unbound vaccines indicate increased stability once the binding was carried out. This pattern was also observed with the RMSF values, more clearly with the first complex, thereby solidifying the complex's stability and indicating the complex chains' flexibility (57). The negative binding, Van der Waals and electrostatic energy values indicate a high binding affinity between protein-protein or protein-ligand interactions (174).…”

Buruli ulcer is a neglected tropical disease that is characterized by non-fatal lesion development. The causative agent is Mycobacterium ulcerans (M. ulcerans). There are no known vectors or transmission methods, preventing the development of control methods. There are effective diagnostic techniques and treatment routines; however, several socioeconomic factors may limit patients’ abilities to receive these treatments. The Bacillus Calmette–Guérin vaccine developed against tuberculosis has shown limited efficacy, and no conventionally designed vaccines have passed clinical trials. This study aimed to generate a multi-epitope vaccine against M. ulcerans from the major facilitator superfamily transporter protein using an immunoinformatics approach. Twelve M. ulcerans genome assemblies were analyzed, resulting in the identification of 11 CD8+ and 7 CD4+ T-cell epitopes and 2 B-cell epitopes. These conserved epitopes were computationally predicted to be antigenic, immunogenic, non-allergenic, and non-toxic. The CD4+ T-cell epitopes were capable of inducing interferon-gamma and interleukin-4. They successfully bound to their respective human leukocyte antigens alleles in in silico docking studies. The expected global population coverage of the T-cell epitopes and their restricted human leukocyte antigens alleles was 99.90%. The population coverage of endemic regions ranged from 99.99% (Papua New Guinea) to 21.81% (Liberia). Two vaccine constructs were generated using the Toll-like receptors 2 and 4 agonists, LprG and RpfE, respectively. Both constructs were antigenic, non-allergenic, non-toxic, thermostable, basic, and hydrophilic. The DNA sequences of the vaccine constructs underwent optimization and were successfully in-silico cloned with the pET-28a(+) plasmid. The vaccine constructs were successfully docked to their respective toll-like receptors. Molecular dynamics simulations were carried out to analyze the binding interactions within the complex. The generated binding energies indicate the stability of both complexes. The constructs generated in this study display severable favorable properties, with construct one displaying a greater range of favorable properties. However, further analysis and laboratory validation are required.

“…Identification of genes and gene pathways involved in adaptive resistance is also vital for developing markers for prediction and diagnosis and should be pursued. Kim and Schneider [48] observed that, "by examining selective sweeps in many endemic areas with different demographic and epidemiologic characteristics" it would be possible to identify factors associated with adaptive resistance to malaria drugs and track epidemiological variables [53][54][55][56]…”

Malaria is a global disease of importance, especially in the sub-Saharan African region, where malaria accounts for great losses economically and to life. Fight to eliminate this disease has resulted in reduced disease burden in many places where the diseases is endemic. Elimination strategies in most places is focus on the use of treated nets and drug application. Exposure of malaria parasites to anti-malaria drugs have led to the evolution of drug resistance in both parasites and host. Development of drug resistance vary but, studies on adaptive drug resistance has implications and consequences. Our knowledge of this consequences are limited but important for the pursuit of an uninterrupted malaria elimination agenda. This chapter draws our attention to this risks and recommends interventions.

Leptospirosis is a tropical and globally neglected zoonotic disease caused by pathogenic spirochetes, Leptospira. Although the disease has been studied for decades, a potent or effective vaccine is not available so far. Efforts are being made to design an efficient vaccine candidate using different approaches. Immunoinformatics approaches have been proven to be promising in terms of time and cost.Here, we used immunoinformatics and structure-based approaches to evaluate antigenic B-and T-cell epitopes present on the leptospiral lipoproteins (LipL).The promiscuous overlapping epitopes (B-cell, T-cell, interferon (IFN)-γ positive, and non-allergens), which can induce humoral, cell-mediated, and innate immunity, were selected to generate a multiepitope chimeric vaccine. To enhance the vaccine immunogenicity, a Toll-like receptor (TLR) agonist was fused to the vaccine with a suitable linker. The chimeric vaccine structure was predicted for molecular docking studies with immune receptors. Moreover, the stability of the vaccine-immune receptor complexes was analyzed by normal mode analysis (NMA). The potency of the vaccine construct was predicted by the immune simulation tool. The study provides additional information toward constructing peptide-based chimeric vaccines against Leptospira.
