Title : Understanding the Determinants to T-cell Receptor Binding in Cancer Immunotherapies.

Abstract : The activity of the adaptive immune system depends on the recognition of foreign antigens by T cells by their specific T cell receptors (TCRs). A correct understanding of the determinants that govern the binding of T cells to cancer neo-antigens is crucial to design better immunotherapies, distinguished by more effective binding profiles and less cross-reactive effects. Our group has recently developed TITAN, a multi-modal deep learning model that predicts the binding affinity between TCRs and epitopes, outperforming the state of the art in this difficult task. Interestingly, TITAN allows to study independently the generalization capabilities to new TCRs and/or epitopes, which previous models have struggled with. Furthermore, to enhance the interpretability of the predictions, TITAN exploits interpretable attention mechanisms that selectively highlight the patterns in the TCR and epitope sequence that are more important to make the prediction. In parallel, we are investigating the use of alternative techniques to enhance prediction transparency, for instance, based on the use of probabilistic graphical models. This is an example of how the combined used of AI and traditional mathematical approaches can result in more performant models able to make great strides into a multitude of fields, including prediction of autoantigens in autoimmune diseases, development of immunotherapies for cancer, or vaccine design.

Title : RNA Three-dimensional Structure and Non-canonical Base Pairing

Abstract : It is well known now that mRNA is not the only form of RNA and RNA performs various gene regulatory and other functions in the cellular environment. These specific functions demand stable three-dimensional structures of various RNA, such as tRNA, ribosome, riboswitch, miRNA, etc. The only secondary structural element of RNA, like 𝞪-helix, 𝞫-sheet, etc. of proteins, is double helix. Traditionally we conceptualize double helix as that proposed by Watson and Crick in 1953 stabilized by specific pairing through hydrogen bonds between A and T (or U in RNA) and those between G and C. Such double helices of DNA are extremely stable and expose different sites of the bases for specific molecular recognition by gene regulatory proteins. In RNA however, these are not possible and nature utilized few types of base pairs completely different from those proposed by Watson and Crick. These non-canonical base pairs have been shown to be specific, stable, capable to form double helix and provide sufficient sites for proper molecular recognition. In this lecture I would be focusing on such non-canonical base pairs from various aspects.

His research interest includes Quantum Chemistry, Molecular Dynamics, Structure-Function correlation of biological macromolecules and development of tools for bioinformatics applications. He has published more than 60 research articles, trained more than 12 doctoral students and developed several bioinformatics softwares namely, NUPARM, BPFIND, PyrHBFIND,RNAHelix etc. He developed techniques in understanding the effects of base sequence on DNA double helices and its interactions with other molecules. It was necessary to analyze 3D structures of different functional RNA molecules after ribosome and several other RNA were solved by x-ray crystallography. Such analysis in terms of different quantitative parameters, such as relative orientation between bases of base pair or between successive base pairs in double helical regions or identification of different types of base pairs in a large complex RNA structure, require specially designed software and were unavailable in such a nascent field. His team developed several software for such analysis and application of those identified several important non-canonical base pairs apart from the Watson-Crick type A:U and G:C. His team used different simulation techniques with classical as well as quantum mechanical methods to understand their properties in terms of strength, stability, dynamics, planarity, etc.

Title :
Novel Nanofluidic Mechanism and Computational Model of the Brain Water Metabolism
Abstract :
Brain water metabolism ensures the processes of cellular communication, transit of the signaling molecules, neurotransmitters, cytokines and substrates, participates in the clearance of pathogenic metabolites. Many neurological conditions that present serious clinical problems arise from altered fluid flow (e.g. Alzheimer’s disease, idiopathic normal pressure hydrocephalus, migraine, traumatic brain injury and stroke). At present, the orthodox theory fails to explain the accumulated experimental evidence and clinical data on the brain water metabolism. Modeling becomes an important approach to testing current theories and developing new working mechanisms. 

A novel computational model of brain water metabolism has been developed and explored. Using an interdisciplinary approach the long-recognized nano-dimentionality of the brain interstitial space is viewed as a nano-fluidic domain with the fluid flow there governed by the slip-flow principles of nano-fluidics. Aquaporin-4 (AQP4) of the astrocyte endfeet membranes ensures kinetic control over water movement across the blood-brain barrier. The pulsatory intracranial pressure presents the driving force behind the transcapillary water flow. The model demonstrates good predictability in respect to some physiological features of brain water metabolism and relevance in explaining clinical conditions. The model may find its use in neuro-biological research, development of the AQP4-targeted drug therapy, optimization of the intrathecal drug delivery to the brain tumours, in a research on a broad spectrum of water-metabolic-disorder-related conditions.

Title : Advances in Neurosurgery- Glimpses of the Role of Technology in the Operating Room
Abstract :
There has been rapid advancements in the use of technology in the operating room by neurosurgeons all over the world. The nature of the biology of the central nervous system in humans is such that being permanent cells, the neurons do not regenerate. Neurosurgeons have been aware of the critical nature and biology of the tissues they deal with and have therefore been at the forefront in adapting new technology to benefit their patients. The technological revolution in neurosurgery has been fueled as much by the developments in computer technology and connectivity as by the advancements in material science and precision engineering. The seminar deals with the use of certain available equipment to demonstrate how clinicians and surgeons have adapted technology to positively impact and improve the lives of their patients.

Title: Diagnosis of Glioma Tumors Using Circulating Cell-Free DNA

Abstract: Gliomas are the most frequent brain tumors, making up about 30% of all brain and central nervous system tumors, and 80% of all malignant brain tumors. Diagnosis of different glioma tumor types and their tumor grade is an essential step to suggest a right treatment for the glioma patients. Existing standard diagnostic technique for glioma tumor includes tissue biopsy, which is a highly invasive and hence a risky technique for the patient’s survival. ‘Liquid biopsy’ is a new and recently developed non-invasive cancer diagnostic technique. This technique includes collection of blood or urine samples and diagnosis of cancer based on analyzing molecular bits or cancer cells that are released from tumor tissue into the blood or urine system. Circulating cell-free DNA (cfDNA) fragments is one those molecular bits that are released into the bloodstream after rapid apoptosis or necrosis of the tumor cells in the cancer patients. Our goal is to do comprehensive study between distinct types of glioma cancer tumors and cfDNA of the respective patients, to elucidate the scope of cfDNA in liquid biopsy technique for glioma diagnosis. We have successfully detected glioma specific mutations such as IDH1, IDH2, PDGFRA, NOTCH1, PIK3R1 and TP53, from cfDNA isolated from the plasma of glioma patients and could relate these mutations to the different tumor grades of glioma. Moreover, we have identified unique gene-gene fusions that provide a personalized drug response to glioma treatment. Our study may help in developing liquid biopsy technique for glioma tumor diagnosis and in its prognosis for monitoring the glioma treatment by non-invasive approach, and will eventually help physicians to decide on the right treatment while bypassing the existing ''wait-and-see' approach of treatment monitoring.

Title: Development of Algorithm for Automated Diagnosis of Leukemia : A Systems Biology Application for Preventive Oncology
Abstract: Bone marrow biopsy has become an integral part of leukemia diagnosis and its treatment. Several advancements are being made towards the analysis of digital images of biopsy samples. Recently FDA approved the procedures of digital health. In tune with that digital image analysis has become propelled. With the advent of high-throughput technologies, scientific community becomes interested to look into the red blood cells (RBCs) for early detection of cancer, including leukemia. The reasons are due to their abundance in peripheral blood and hence, easily accessible compared to bone marrow biopsy procedure. High magnification and high-resolution electron microscopy based ultra-structural analysis of RBCs already proved the utility of the hypothesis about a decade ago. However, in clinical set-up, electron microscopy based procedures are the major bottleneck in implementation of early detection of leukemia. Algorithm based computer vision may be suitable to overcome this limitation. To fill the existing gap a user-friendly MatLab coding is developed for automated analysis of RBC images. RBC images from both normal and leukemia were analyzed with the developed code. Each RBC cells were analyzed individually for each samples of normal and leukemia. So in the output cellular characteristics namely, radius, perimeter, area, convexity, solidity were represented in a quantitative manner. Comparison of mean values between normal and leukemia groups for corresponding variables showed statistical significance (p<0.05). Thus, the developed code successfully distinguishes between RBC cells of leukemia and normal. We hope that this RBC based developed code would be useful in identifying early stage of leukemia in an individual patient; however, for this ~100 RBC cells are needed to be analyzed. Thus it is expected that the developed code may play a role in preventive oncology.

# Speaker: Prof. Jan-Hendrik (Jannie) Hofmeyr
Title: The Metabolic Marketplace: How the cellular economy of supply and demand is regulated
Abstract: A central tenet of systems biology is that organisms, cells, genes and proteins are complex structures whose relationships and properties are largely determined by their functional organisation. In terms of functional organisation cellular metabolism can be regarded as a chain of coupled factories: a catabolic factory transforms nutrients into carbon skeletons and captures chemical energy and reducing power. These catabolic products serve as input to an anabolic factory that synthesizes the building blocks for macromolecular syntheses (amino acids, nucleotides, simple lipids, etc.). The factories for protein, polynucleotide, complex carbohydrate and lipid synthesis form the end of the chain and lead to growth. I show how this view of the functional organisation of the cell underlies a quantitative formalism and a general theory for understanding the cell as an integrated molecular economy of coupled supply and demand systems that have evolved regulatory mechanisms that enable them to fulfil specific functions such as control of flux or homeostatic maintenance of metabolite concentrations.
Jan-Hendrik (Jannie) Hofmeyr is Emeritus Professor of Biochemistry and has been a member of the Biochemistry Department at the Stellenbosch University since 1975. He obtained his Ph.D. in 1986 at the University of Stellenbosch. His research of the past 40 years has been in the fields of metabolic control analysis and computational systems biology where his main focus has been the understanding of the regulatory design of metabolism. He also co-directed the Centre for Complex Systems in Transition where an additional research focus was the functional organisation that underlies cellular self-fabrication. He is a Fellow and was President of the Royal Society of South Africa, and is a member of the Academy of Science of South Africa. He is a founder member and served as Vice President of the International Society for Code Biology.
