The blood-brain barrier (BBB) plays a vital role in protecting the central nervous system (CNS) by preventing the entry of harmful pathogens from the bloodstream. However, this barrier also presents a significant obstacle when it comes to delivering drugs for the treatment of neurodegenerative diseases and brain cancer. Recent breakthroughs in nanotechnology have paved the way for the creation of a wide range of nanoparticles (NPs) that can serve as carriers for diagnosis and therapy.

Neuroimmunometabolism describes how neuroimmune cells, such as microglia, adapt their intracellular metabolic pathways to alter their immune functions in the CNS. Emerging evidence indicates that neurons also orchestrate the microglia mediated immune response through neuro-immune crosstalk perhaps through metabolic signalling. However, little is known about how the brain's metabolic microenvironment and microglial intracellular metabolism orchestrate the neuroimmune response in healthy and diseased brains.

The outbreak of COVID-19 has opened up new avenues for exploring the importance of vitamin D in immunity, in addition to its role in calcium absorption. Recently, vitamin D supplementation has been found to enhance T regulatory lymphocytes, which are reduced in individuals with COVID-19. Increased risk of pneumonia and increases in inflammatory cytokines have been reported to be major threats associated with vitamin-D deficiency.

PPTC7 is a mitochondrial phosphatase that is essential for mitochondrial biogenesis, metabolism, protein content maintenance and transport. While the mitochondrial roles of PPTC7 are well-characterized, its roles outside the mitochondria are unclear. Here we identified a non-mitochondrial role for PPTC7 in regulating epidermal growth factor receptor (EGFR) trafficking.

Plants defend against chewing herbivores by up-regulating jasmonic acid (JA) signaling, which activates downstream signaling cascades and produces numerous secondary metabolites that act as defense molecules against the herbivores. Although secondary metabolism always remains a focus of research, primary metabolism is also reported to be realigned upon herbivory. However, JA signaling-mediated modulation of primary metabolites and their metabolic pathways in plants are mostly unexplored.

In the past decade, a major goal in biomedical research has been to understand why individuals differ in disease susceptibility, disease dynamics, and progression. In many pathologies, this variability stems from evolved immune mechanisms that resist inflammatory stress from various diseases that have been encountered throughout life. These may provide advantages against other diseases, reduce comorbidities, and enhance longevity.

Department of Life Sciences, School of Natural Sciences, Shiv Nadar Institution of Eminence, Gautam Buddha Nagar, Uttar Pradesh, India.

The emergence of new coronavirus variants and concerns about vaccine effectiveness against these novel variants emphasize the need for broad-spectrum therapeutics targeting conserved coronaviral non-structural proteins. Accordingly, a virtual library of 178 putative inhibitors targeting SARS-CoV-2 Papain-like protease (PL) was compiled through a systematic review of published literature and subsequently screened using molecular docking. Selected hits were analyzed for protease inhibitory activities, binding strength, and antiviral activities against HCoV229E-based surrogate system and subsequently against SARS-CoV-2 for validation.
