Eosinophils and Basophils in Bullous Pemphigoid
Bullous pemphigoid (BP) is an autoimmune blistering skin disease, of which the incidence has increased in recent years. BP is characterized by circulating IgG and IgE autoantibodies against the hemidesmosomal proteins BP180 and BP230.

Defining Premenstrual Syndrome
Premenstrual Syndrome (PMS) is a complex physiological and psychological condition that affects a significant number of women during their reproductive years. Although the exact etiology of PMS remains unclear, its symptoms, including mood swings, bloating, irritability, and fatigue, can significantly impair the quality of life for affected individuals. The management of PMS traditionally involves pharmacological interventions; however, emerging evidence suggests that exercise may offer a valuable non-pharmacological approach to alleviate PMS symptoms.

Association of Obstructive Sleep Apnea with Hypertension
Hypertension (HT) is a worldwide public health issue and an essential risk factor for cardiovascular and cerebrovascular diseases. Obstructive sleep apnea (OSA) is a condition characterized by recurrent episodes of apnea and hypopnea as a consequence of partial or complete obstruction of the upper airways due to anatomic and/or functional disturbances.

Genetics of Alopecia Areata
Alopecia areata (AA) is a chronic, non-scarring, immune-mediated skin disease that affects approximately 0.5–2% of the global population. The etiology of AA is complex and involves genetic and environmental factors, with significant advancements in genetic research occurring. In addition to well-known genes such as PTPN22, CTLA4, and IL2, which have been widely supported as being associated with AA, an increasing number of specific gene-related loci have been discovered through advances in genetic research.

Nanoparticles in the Intestinal Epithelial Cell Membrane
Intestinal epithelial cells are the most abundant epithelial cells in the intestine, accounting for 90–95% of intestinal cells. They are columnar cells with hair-like projections called microvilli on the apical membrane, which greatly increase the surface area available for absorption. The transintestinal cell pathway refers to the process in which nanoparticles pass through apical and basolateral membranes via intercellular transport and then discharge from the basement membrane to the extracellular space. The entire process can be divided into three stages: the uptake of nanoparticles in the apical membrane of intestinal epithelial cells, the transport of endosomes in the cytoplasm and the exocytosis of nanoparticles in the basement membrane.

Possible Evolutionary Origin of Alzheimer’s Disease
The enormous, 2–3-million-year evolutionary expansion of hominin neocortices to the current enormity enabled humans to take over the planet. However, there appears to have been a glitch, and it occurred without a compensatory expansion of the entorhinal cortical (EC) gateway to the hippocampal memory-encoding system needed to manage the processing of the increasing volume of neocortical data converging on it. The resulting age-dependent connectopathic glitch was unnoticed by the early short-lived populations. It has now surfaced as Alzheimer’s disease (AD) in today’s long-lived populations. With advancing age, processing of the converging neocortical data by the neurons of the relatively small lateral entorhinal cortex (LEC) inflicts persistent strain and high energy costs on these cells. This may result in their hyper-release of harmless Aβ1–42 monomers into the interstitial fluid, where they seed the formation of toxic amyloid-β oligomers (AβOs) that initiate AD. At the core of connectopathic AD are the postsynaptic cellular prion protein (PrPC). Electrostatic binding of the negatively charged AβOs to the positively charged N-terminus of PrPC induces hyperphosphorylation of tau that destroys synapses. The spread of these accumulating AβOs from ground zero is supported by Aβ’s own production mediated by target cells’ Ca2+-sensing receptors (CaSRs).

Microbiome–Gut–Mucosal–Immune–Brain Axis and Autism Spectrum Disorder
Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder characterised by deficits in social interaction and communication, as well as restricted and stereotyped interests. Due of the high prevalence of gastrointestinal disorders in individuals with ASD, researchers have investigated the gut microbiota as a potential contributor to its aetiology. The relationship between the microbiome, gut, and brain (microbiome–gut–brain axis) has been acknowledged as a key factor in modulating brain function and social behaviour, but its connection to the aetiology of ASD is not well understood.

Effects of Tirzepatide in Spectrum of Metabolic Diseases
The prevalence of metabolic diseases including type 2 diabetes (T2D), obesity and non-alcoholic fatty liver disease (NAFLD) increases globally. This highlights an unmet need for identifying optimal therapies for the management of these conditions. Tirzepatide is a novel dual incretin receptor agonist (twincretin) that activates both glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors.

Animal-Associated Methicillin-Resistant Staphylococcus aureus
Methicillin-resistant Staphylococcus aureus (MRSA) remains an important etiological factor of human and animal infectious diseases, causing significant economic losses not only in human healthcare but also in the large-scale farming sector. The constantly changing epidemiology of MRSA observed globally affects animal welfare and raises concerns for public health. High MRSA colonization rates in livestock raise questions about the meaning of reservoirs and possible transmission pathways, while the prevalence of MRSA colonization and infection rates among companion animals vary and might affect human health in multiple ways.

Rodent Models of Dilated Cardiomyopathy and Heart Failure
Even with modern therapy, patients with heart failure only have a 50% five-year survival rate. To improve the development of new therapeutic strategies, preclinical models of disease are needed to properly emulate the human condition. Determining the most appropriate model represents the first key step for reliable and translatable experimental research. Rodent models of heart failure provide a strategic compromise between human in vivo similarity and the ability to perform a larger number of experiments and explore many therapeutic candidates.
