Diet-Induced Insulin Resistance
Insulin resistance (IR) is defined as the decreased ability of insulin to insert the glucose transporter (glut4) on the cell membrane facilitating glucose entry into body cells. IR in the hepatocytes is associated with increased de novo lipogenesis and gluconeogenesis, leading to hypertriglyceridemia and hyperglycemia.

Common Variable Immunodeficiency
Inborn errors of immunity (IEI) are multifaced diseases which can present with a variety of phenotypes, ranging from infections to autoimmunity, lymphoproliferation, and neoplasms. In recent decades, research has investigated the relationship between autoimmunity and IEI. Autoimmunity is more prevalent in primary humoral immunodeficiencies than in most other IEI and it can even be their first manifestation. Among these, the two most common primary immunodeficiencies are selective IgA deficiency and common variable immunodeficiency (CVID).

SARS-CoV-2 Variant-Specific Gastrointestinal Symptoms of COVID-19
The gastrointestinal (GI) tract may be a significant entrance or interaction site for SARS-CoV-2; therefore, the gut mucosal immune system participates in virus interaction as a first-line physical and immunological defense, leading to GI involvement and symptoms. The pattern of symptoms changed during the virus evolution, since the data provided a current and thorough picture of the symptoms experienced by SARS-CoV-2 infected people, and variations in symptom patterns occurred as the Alpha, Delta, and Omicron variants have spread. Since the beginning of the pandemic, GI symptoms have been linked to SARS-CoV-2 infections, even though most infected people do not report them.

Peptide Nucleic Acid
Peptide nucleic acid (PNA) is an artificial DNA analog in which the negatively charged phosphodiester backbone is replaced by a charge-neutral pseudopeptide backbone. PNA exhibits several conformational flexibilities. It can adopt the A and B helical structures upon binding to target RNA and DNA, respectively, and form antiparallel and parallel duplexes. The antiparallel duplex is generally more stable than the parallel one.

Frontotemporal-TDP Neurocognitive Disorders
Frontotemporal lobar degeneration (FTLD) belongs to a heterogeneous group of highly complex neurodegenerative diseases and represents the second cause of presenile dementia in individuals under 65. Frontotemporal-TDP is a subgroup of frontotemporal dementia characterized by the aggregation of abnormal protein deposits, predominantly transactive response DNA-binding protein 43 (TDP-43), in the frontal and temporal brain regions. These deposits lead to progressive degeneration of neurons resulting in cognitive and behavioral impairments. Limbic age-related encephalopathy (LATE) pertains to age-related cognitive decline primarily affecting the limbic system, which is crucial for memory, emotions, and learning.

Molecular Mechanisms and Signaling Pathways in Gastric Cancer
Gastric cancer (GC) is common but often diagnosed late. Advances in chemotherapy, targeted therapy, and immunotherapy offer promising treatments. Perioperative chemotherapy is now the standard for resectable gastric cancer. Progress has also been made in treating metastatic disease using targeted immunotherapies. Molecular biomarkers such as programmed cell death protein ligand 1 (PD-L1), microsatellite instability (MSI), and human epidermal growth factor receptor 2 (HER2) guide personalized treatment approaches.

mRNA, Live-Attenuated/Chimeric and VLP-Based Vaccines
Respiratory syncytial virus (RSV) is an enveloped, negative-sense, single-stranded RNA virus causing seasonal infections in a biphasic age distribution, affecting more frequently children until the age of 2 years with a higher frequency across the age spectrum from 6 weeks to 6 months, as well as older adults due to the reduction of immunity.

Trained Immunity in Atherosclerosis
Coronary artery disease (CAD) is the leading cause of death worldwide. It is a result of the buildup of atherosclerosis within the coronary arteries. The role of the immune system in CAD is complex and multifaceted. The immune system responds to damage or injury to the arterial walls by initiating an inflammatory response. However, this inflammatory response can become chronic and lead to plaque formation. Neutrophiles, macrophages, B lymphocytes, T lymphocytes, and NKT cells play a key role in immunity response, both with proatherogenic and antiatherogenic signaling pathways.

ErbB Receptors
The activation of members of the Epidermal Growth Factor Receptor (EGFR) family (including ErbB) triggers pathways that have significant effects on cellular processes and have profound consequences both in physiological and pathological conditions. Within the nervous system, the neuregulin (NRG)/ErbB3 signaling plays a crucial role in promoting the formation and maturation of excitatory synapses. Noteworthy is ErbB3, which is actively involved in the process of cerebellar lamination and myelination. All members of the ErbB-family, in particular ErbB3, have been observed within the nuclei of various cell types, including both full-length receptors and alternative variants.

Genetic Therapy in Oncology
The impressive advances in the knowledge of biomarkers and molecular targets has enabled significant progress in drug therapy for crucial diseases such as cancer. Specific areas of pharmacology have contributed to these therapeutic outcomes—mainly targeted therapy, immunomodulatory therapy, and gene therapy.
