Studies On The Roles Of Intracellular Ca2+ And Reactive Oxygen Species During CD4+ T Cell Activation : Influence Of Signal Strength
(2011-03-08)Optimal CD4+ T cell activation is key to the generation of a productive immune response. Naïve circulating CD4+ T cells are quiescent under normal conditions and undergo activation only upon encounter of the T cell receptor ... -
Studies on the roles of rffG and rfbB encoding dTDP-glucose 4,6- dehydratase in Salmonella Typhimurium
Salmonellosis is a major health concern which causes significant morbidity and mortality worldwide. Infection with Salmonella Typhimurium leads to self-limiting diarrhea in healthy individuals and invasive disease in ... -
Studies On The Structural And Biological Properties Of Rotavirus Enterotoxigenic Non-structural Protein 4 (NSP4)
(2013-04-01)Rotavirus is the major cause of infantile gastroenteritis. Each year more than 600,000 young children are estimated to die in developing countries throughout the world. Rotavirus infection can be either symptomatic or ... -
Studies on Δ40p53 mediated regulation of specific coding and non-coding RNAs: Consequences on cellular processes
p53 is a crucial transcriptional regulator which influences almost every possible pathway that impinges on the life of a cell. As expected of such an instrumental protein, the molecular network of p53 is as diverse as it ... -
Study of Ca2+-Mediated Signal Transduction During Embryogenesis In Sandalwood (Santalurm Album L.) And Characterization Of An Early Development-Specific CDPK
(Indian Institute of Science, 2005-12-08)Calcium ion plays a pivotal role as second messenger during signal/response coupling in plant cells (Trewavas, 1999). Elevations of cytosolic Ca2+ occur in plants as a consequence of abiotic and biotic stresses, environmental ... -
A study of extracellular matrix dynamics in epithelial cancer progression with a special focus on ovarian cancer spheroidogenesis
Epithelial ovarian cancer (EOC) is one of the most debilitating gynecological cancers in women worldwide due to its insidious symptoms. The predominant subtype of ovarian cancer: high-grade serous ovarian carcinoma (HGSOC), ... -
Study Of Rpb4, A Component Of RNA Polymerase II As A Coordinator Of Transcription Initiation And Elongation In S. Cerevisiae
(2017-05-24)RNA polymerase II (Pol II) is the enzyme responsible for the synthesis of all mRNAs in eukaryotic cells. As the central component of the eukaryotic transcription machinery, Pol II is the final target of transcription ... -
A Study Of The Roles Played By The Trishanku Gene In The Morphogenesis Of Dictyostelium Discoideum
(2011-02-22)A hallmark feature of Dictyostelium development is the establishment and maintenance of precise cell-type proportions. In the case of D. discoideum, roughly 20% of the cells that aggregate form the stalk while the remaining ... -
A Study On The Mechanism Of Initiator tRNA Selection On The Ribosomes During Translation Initiation And Rescue Of The Stalled Ribosomes By SsrA In Escherichia Coli
(2013-02-07)The studies reported in this thesis describe the work done in the area of translation initiation where a previously unknown role of multiple copies of initiator tRNA in E. coli has been reported. Also the role of SsrA ... -
A Study On The Roles Of The Ras Activation Pathway During Interferonγ Mediated Functional Responses And Acetaminophen-induced Liver Injury In Mice
(2010-12-07)Interferons (IFNs) perform a wide range of biological activities: anti-microbial, anti-proliferative, immunomodulatory etc. The IFN family includes three main classes: Type I, Type II and the recently identified Type III. ... -

Studying the role of small GTPase Rab14 in the regulation of endosomal function
The endomembrane system and their associated membrane trafficking are fundamental features of eukaryotic cell biology. These processes are regulated by small GTP-binding proteins that acts as molecular switches to ... -
Substrate interrogation of the CRISPR-Cas12a endonuclease reveals an unexpected functional plasticity
Substrate interrogation of the CRISPR-Cas12a endonuclease reveals an unexpected functional plasticity Currently, Cas9 and Cas12a (also known as Cpf1) are the sole members of a large family of RNA-guided nucleases that ... -
Substrate Specificity Determinants of Class III Nucleotide Cyclases
(2018-07-31)Cyclic AMP and cyclic GMP (cAMP and cGMP) are important second messengers in key signal-transduction pathways that mediate various physiological functions in bacteria and eukaryotes. Adenylyl Cyclases (ACs) and Guanylyl ... -
Subthreshold Conductances Regulate Theta-Frequency Local Field Potentials and Spike Phase
(2018-02-21)Local field potentials (LFPs), extracellular potentials that reflect localized electrical activity, have long been used as a window to understand the behavioural dependence and mechanistic aspects of brain physiology. A ... -
Super-Resolution Imaging Reveals Localization and Regulation of Nanoscale Machinery Involved in the Amyloidogenic Pathway
Amyloid Precursor Protein (APP) is a key player in Alzheimer’s disease (AD). Despite intuitive insights into differential proteolysis of APP, there is a little understanding of how the amyloidogenic machinery is distributed ... -
Suppression of epileptiform activity by lactate through HCA1 and GIRK channel activation in rat subicular pyramidal neurons
In the present study, we report a lactate-induced hyperpolarization and reduction of epileptiform activity in subicular weak burst firing and regular firing neurons using patch clamp electrophysiology. We showed the ... -
