Astroglial development as the basis for the effects of early life stress on adult depressive-like behavior
This thesis investigates the enduring effects of early-life stress, specifically maternal separation, on astroglial population and the subsequent behavioral outcomes in adult mice. While the persistent impact of early-life ... -
The benefits and costs of flexible alternative reproductive tactics in Oecanthus henryi
Alternative reproductive tactics (ARTs) are distinct phenotypes that individuals of a species use to maximize reproductive success. This thesis investigates the persistence and adaptive value of flexible ARTs in male tree ... -
Characterization of a Staphylococcus aureus multi-enzyme complex involved in the phenotypic switch and host-pathogen interactions
RNA homeostasis is maintained by synchronizing RNA synthesis and RNA degradation. These processes are synchronized to growth conditions and environmental stimuli, thus enabling bacterial survival in diverse environmental ... -
Characterizing the link between dynamics and function in proteins that violate the structure-function paradigm
The structure-function paradigm states that the three-dimensional structure of a protein is dictated by its amino acid sequence, which influences its function. However, this paradigm fails to explain the behaviour of ... -
Cyclic nucleotide-binding proteins in mycobacteria
Mycobacterium tuberculosis, one of the leading causes of death worldwide even today, employs the second messenger cAMP extensively for its pathogenicity and persistence. Intracellular and extracellular levels of cAMP in ... -
Deciphering canonical and non-canonical role of splicing factor Prp16 in pathogenic yeast C. neoformans
RNA splicing is a ubiquitous process during eukaryotic gene expression, where non-coding introns are removed from primary transcripts to form functional mRNA. This vital process is carried out by the spliceosome, a large ... -
Deciphering Hypoxic Adaptations in Cutibacterium acnes using Multi-omics Profiling and Systems Modelling
The opportunistic skin anaerobe Cutibacterium acnes (C. acnes) contributes to skin homeostasis with its antioxidant and immunomodulatory activities. C. acnes (formerly known as Propionibacterium acnes) is an aerotolerant, ... -
Deciphering the evolutionary ecology of snake venoms and its impact on snakebite therapy in India
Venom, being an adaptive trait, has propelled the expansion of snake lineages across diverse habitats, such as the biogeographically distinct Indian landscapes. Natural selection optimises the potency, composition and ... -
Deciphering the mechanism behind the division of the Salmonella containing vacuole (SCV) and the immunomodulation strategy employed by Salmonella Typhimurium
The genus Salmonella represents flagellated, Gram-negative, rod-shaped anaerobic bacteria which is a leading cause of food-borne illness and causes enteric disease in a wide range of animals. In humans and several warm-blooded ... -
Deciphering the role of DJ-1 homologs in alleviating carbonyl and oxidative stress in Arabidopsis thaliana
The present study aims to elucidate the physiological role of plant DJ-1 homologs in Arabidopsis thaliana under various abiotic stress conditions. It seeks to provide deeper insights into the diverse functions of plant ... -
Deep Mutational Scanning Analyses of Protein Stability and Function
Full text Embargo up to Sep 2026 Protein stability is critical to understanding protein function, folding, and interactions within living organisms. It plays a key role in protein engineering, where designing stable ... -
Deep mutational scanning to enhance immunogenicity and map antibody responses to HIV-1
Vaccines have proven effective against numerous viral diseases, yet the development of a successful vaccine for Human Immunodeficiency Virus (HIV-1) remains elusive. A key immunogen for vaccine design is the surface ... -
Design and characterization of stabilized mutants of the SARS-CoV-2 Receptor Binding Domain
The global pandemic caused by SARS-CoV-2 has resulted in millions of deaths worldwide, highlighting the urgent need for effective vaccines. The trimeric spike glycoprotein, particularly the receptor-binding domain (RBD), ... -
Design of Immunogens Derived from the Conserved Stem of Influenza Virus Hemagglutinin
Influenza viruses can cause respiratory illnesses and are very contagious, leading to either pandemics or seasonal epidemics and resulting in significant mortality and morbidity rates. The main symptoms of the influenza ... -
Design, Biophysical Characterization, and Serum Epitope Mapping of SARS-CoV-2 RBD Vaccine Immunogens
Embargo up to Jan 9, 2026 -
Determinants of protein stability and function inferred from saturation mutagenesis and next-generation sequencing
Proteins play a central role in all biological processes. Despite a similar underlying composition, they exhibit immense diversity in structures and functions, a subject of great interest. The research presented in this ... -
Distinct extracellular signatures of active-dendritic chemical and electrical synapses differentially contribute to ripple-frequency oscillations
Extracellular field potentials across brain regions exhibit distinct signatures that depend on several region-specific attributes, including spatiotemporal patterns of afferent inputs, anatomical and physiological properties ... -
Eco-evolutionary consequences of bacterial predation
Predator-prey interactions pervade all ecosystems at all levels of biological organization. Ample research using higher eukaryotes has demonstrated the role of predator-prey interactions on the evolution of ecological and ... -
Electrophysiological studies investigating drug effects on hHCN1 channels and Unravelling pore dynamics in Pannexin channels
Hyperpolarization-activated cyclic nucleotide-gated (HCN) ion channel stands out for its unique characteristics, including sensitivity to transmembrane voltage and cyclic nucleotides, as well as its non-selective passage ... -
Elucidating mechanisms regulating GC-C signalling in colorectal cancer
Colorectal cancer is the third most frequently diagnosed cancer and the second major cause of cancer death worldwide. Classical therapies for treating colorectal cancer are mostly nonspecific and, therefore, are associated ...
