Characterization of Thymocyte Subpopulations and Mechanistic Insights during Various Modes of Thymic Atrophy
T lymphocytes along with B lymphocytes constitute the adaptive immune system, which is critical for host defence. The progenitors of T cells arise in the bone marrow and the sequential development of T cells occurs in the ... -
Elucidating the Roles of Lon Protease and its Substrate, MarA, in Response to salicylate and other Compounds in Escherichia coli
(2017-11-28)Cytosolic protein degradation is crucial for cellular homeostasis as it orchestrates protein turnover by destruction of misfolded, unstable and abnormal proteins. This process has two main stages: (i) an ATP-dependent stage ... -
Functional characterization of Salmonella Typhimurium encoded Cold Shock Protein E during stress responses, biofilm formation and virulence
Overall, this study reports novel functional roles of S. Typhimurium encoded CspE during bile resistance, biofilm formation and in vivo virulence. It also establishes importance of an uncharacterised protein YciF, implicating ... -
Host responses in Fas-deficient autoimmune-prone lpr mice upon Salmonella Typhimurium infection
Autoimmune diseases can potentially pre-dispose an individual to infections. On the other hand, infections can trigger, exacerbate or ameliorate autoimmunity. Autoimmune Lymphoproliferative Syndrome (ALPS) is a rare genetic ... -
Immunomodulatory effects of 7-hydroxy frullanolide, a plant-based sesquiterpene lactone, in inhibiting immune cell responses and roles of disease and vaccination outcomes on Covid-19 mortality
Immunomodulation is a process by which the immune response of the host is either enhanced or suppressed due to various factors which either protects or makes the host more susceptible to particular diseases. Immunomodulators ... -
Peptidase N, A Major Aminopeptidase Belonging To The M1 Family : Biochemical And Functional Implications
(2009-08-05)Intracellular protein degradation is required for maintaining the cellular proteome and regulating cellular processes. This pathway involves proximal ATP-dependent proteases that unfold and translocate proteins targeted ... -
Studies on inflammatory responses: Roles of Interferon-gamma in macrophage activation and Nitric oxide synthase 2 during Salmonella Typhimurium infection-induced sepsis
Inflammation is a complex set of immune responses that is critical for survival during injury or infection. It is also crucial for maintenance of tissue homeostasis under myriad conditions caused by cellular stress and ... -
Studies on Novel Functional Responses of Mouse Peritoneal Macrophages to Interferon-gamma : Roles of Nitric Oxide Synthase 2
(2018-04-18)Interferons are known cytokines that display antiviral, anti-proliferative and immuno-modulatory functions in the host. Interferon-gamma (Ifnγ) is the only type II family interferon that binds to the heterodimeric receptor ... -
Studies On The Functional Roles Of Peptidase N, A M1 Family Member, During Stress And Infection
(2014-08-11)The cytosolic protein degradation pathway, performed by ATP-dependent proteases and ATP-independent peptidases, plays important roles in several cellular activities, e.g. cell division, cell cycle progression, intracellular ... -
Studies On The Mechanisms Involved In Thymic Atrophy During Salmonella Enterica Serovar Typhimurium Infection
(2015-09-04)T lymphocytes are an essential component of the adaptive immune response and are highly versatile in function. Each T cell has a unique T cell receptor that can recognize an antigenic peptide in the context of the major ... -
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 ... -
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. ... -
Systems biology approach to dissect Salmonella-host interactions
Systems understanding of the biological data is required to capture the complex biochemical information when a pathogen interacts with its host. Such interactions are dynamic and complex, especially because various components ...
