Cell Signaling

Interferons (IFNs) are a class of small immunological proteins that are secreted by infected cells during viral or bacterial infections to combat and prevent infection propagation [1]. They play important roles in triggering signal cascade processes inside the cell that activate other immune cells and limit viral multiplication.

Two distinct, but intertwining, threads of inquiry have demonstrated that the PDE4, or cAMP-selective, phosphodiesterases, have an essential role in human cognition, learning and memory. Study of genetically-modified preclinical models, and of humans with mutations in the PDE4D gene, has provided some of the most rigorous proof of the importance of PDE4 signaling in the CNS. More recently, clinical trials of PDE4-selective inhibitors have shown promising clinical activity in disorders of cognition and memory.

The incidence and prevalence of autoimmune hepatitis (AIH) globally is 1.28 per 100,000 population-years (95% CI, 1.01-1.63) and 15.65 per 100,000 population (95% CI, 13.42-18.24), respectively [1]. The incidence and prevalence in children is 0.4 and 3.0 cases per 100,000 children [2], and in adults 17 per 100,000 [3,4].

Sweat, an exocrine fluid secreted (sweat gland tissue of the eccrine and apocrine glands) by skin has an indispensable function for regulating body temperature and skin hydration [1]. The eccrine gland performs 90% of sweat secretion and secretory fluid of eccrine glands consists of 99% water and 1% inorganic substances.

Camping trips are often a lot of work, especially with children. Purchasing supplies, finding a location, and dealing with scary animals are often just too much. Inspired by so many films, my family instead set up a tent to camp in the backyard.

Attention deficit hyperactivity disorder (ADHD) is a complex behavioral disorder characterized by hyperactivity, increased impulsivity, and inattention [1-3]. Methylphenidate (MPD) is the most
commonly prescribed psychostimulant for management and treatment of ADHD [3-7].

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related deaths [1]. However, significant improvements in the past decades have been achieved with improved outcomes [2-4]. Several mutations have been described as promoters of oncogenesis, and specific treatments are available, including those for Epidermal Growth Factor (EGFR) mutations [4].

Influenza A virus (IAV) and Streptococcus pneumoniae (SPn) are two major respiratory pathogens in humans. IAV infection alone is often self-limited, and SPn colonization can be found in 5-90% of healthy individuals, as normal flora [1,2].

CD226 is a transmembrane glycoprotein with a well-defined structural organization, which is primarily expressed on natural killer (NK) cells, cytotoxic T cells, and some subsets of B cells [1,2]. Its primary structure consists of an extracellular domain, a transmembrane domain, and a cytoplasmic tail [1]. Each of these domains contributes to the protein's overall function.

Myeloid cell leukemia-1 (MCL1) is an anti-apoptotic member of the B-cell lymphoma 2 (BCL- 2) family and plays a key role in cancer cell survival and resistance to therapy [1,2]. MCL1 is often
overexpressed in cancers such as leukemia, lymphoma, and solid tumors, allowing cancer cells to evade apoptosis and resist conventional treatments.

In biomedical research, achieving single-cell resolution in investigation of cellular systems is of paramount importance. Ongoing research efforts to explore and decode the heterogeneity in cellular phenotype, functionality, genomics, epigenetics, and transcriptomics in biological systems have propelled significant technological advancements through innovative breakthroughs [1-3].

Metal nanoclusters, consisting of a few to a few hundreds of metal atoms, have been of great scientific interest due to their potential applications in areas like bio-labeling and catalysis [1-9].

Arrestins were discovered as key players in the conserved two-step homologous desensitization of G protein-coupled receptors (GPCRs): they specifically bind active phosphorylated GPCRs, precluding their coupling to cognate G proteins, thereby stopping (“arresting”) G protein-mediated receptor signaling [1].
