Hippocampal Formation and Unique Properties of CA2 Region
Parkinson’s disease (PD) is a neurodegenerative disease that affects both motor and non-motor functions. Although motor impairment is a prominent clinical sign of PD, additional neurological symptoms may also occur, particularly in the preclinical and prodromal stages. Among these symptoms, social cognitive impairment is common and detrimental. Interestingly, the hippocampal CA2 region, with its unique properties, has attracted the attention of scientists due to its potential association with social cognitive functions.

Tumour-Associated Carbohydrates as Cancer Targets
Glycans are essential players involved in the interaction between cells and the microenvironment, making them ideal targets for the development of new therapies against infections and cancer. Since they modulate membrane receptor affinities, immune recognition, protein-protein interactions, and cell signaling, among others, glycans have been shown to play a relevant role in normal and malignant cell behaviour. Therefore, the alteration of the glycophenotype derived from malignant transformation is one of the adaptive mechanisms that provides tumour cells with growth advantages over normal cells, selected in order to circumvent the control mechanisms of the tissue microenvironment and ensure tumour survival.

TLR9
Toll-like receptor 9 is a protein that in humans is encoded by the TLR9 gene. TLR9 has also been designated as CD289 (cluster of differentiation 289). It is a member of the toll-like receptor (TLR) family. TLR9 is an important receptor expressed in immune system cells including dendritic cells, macrophages, natural killer cells, and other antigen presenting cells. TLR9 preferentially binds DNA present in bacteria and viruses, and triggers signaling cascades that lead to a pro-inflammatory cytokine response. Cancer, infection, and tissue damage can all modulate TLR9 expression and activation. TLR9 is also an important factor in autoimmune diseases, and there is active research into synthetic TLR9 agonists and antagonists that help regulate autoimmune inflammation.

Neoglycoliposomes Bearing Arborescent Architectures
This entry highlights systematic progress in the design of synthetic glycolipid (neoglycolipids) analogs evolving from the conventional architectures of natural glycosphingolipids and gangliosides. Given that naturally occurring glycolipids are composed of only one hydrophilic sugar head-group and two hydrophobic lipid tails embedded in the lipid bilayers of the cell membranes, they usually require extraneous lipids (phosphatidylcholine, cholesterol) to confer their stability. In order to obviate the necessity for these additional stabilizing ingredients, recent investigations have merged dendrimer chemistry with that of neoglycolipid syntheses.

Gap Junction in the Retina
Gap junctions (GJs) are not static bridges; instead, GJs as well as the molecular building block connexin (Cx) proteins undergo major expression changes in the degenerating retinal tissue. Various progressive diseases, including retinitis pigmentosa, glaucoma, age-related retinal degeneration, etc., affect neurons of the retina and thus their neuronal connections endure irreversible changes as well.

Inflammation and Cancer
Chronic inflammation exerts a pivotal role in cancer development, progression, and prognosis. This entry delves into the intricate association between inflammation and cancer, elucidating its triggers, mechanisms, and far-reaching consequences. Chronic infections, environmental pollutants, and lifestyle factors can initiate and sustain inflammation, while inflammatory cells, mediators, and pathways orchestrate cancer-related processes. This interplay molds the tumor microenvironment, fosters therapeutic resistance, and negatively impacts prognosis. Understanding inflammation's role in cancer not only enhances our comprehension of tumorigenesis but also offers potential avenues for novel prevention and treatment strategies, ultimately promising a brighter future in the fight against this formidable disease.

TRPA1 Role in Inflammatory Disorders
The transient receptor potential ankyrin 1 (TRPA1), a member of the TRP superfamily of channels, is primarily localized in a subpopulation of primary sensory neurons of the trigeminal, vagal, and dorsal root ganglia, where its activation mediates neurogenic inflammatory responses. The TRPA1 pathway could be a protective mechanism to detect and respond to harmful agents in various pathological conditions, including several inflammatory diseases.

Pathophysiology of Disseminated Intravascular Coagulation in Sepsis
Sepsis is a major global health problem that results from a dysregulated and uncontrolled host response to infection, causing organ failure. Despite effective anti-infective therapy and supportive treatments, the mortality rate of sepsis remains high. Approximately 30–80% of patients with sepsis may develop disseminated intravascular coagulation (DIC), which can double the mortality rate. There is currently no definitive treatment approach for sepsis, with etiologic treatment being the cornerstone of therapy for sepsis-associated DIC. Early detection, diagnosis, and treatment are critical factors that impact the prognosis of sepsis-related DIC.

Treatment for Diabetes Complications
Diabetes mellitus is a common disease affecting more than 537 million adults worldwide. The microvascular complications that occur during the course of the disease are widespread and affect a variety of organ systems in the body. Diabetic retinopathy is one of the most common long-term complications, which include, amongst others, endothelial dysfunction, and thus, alterations in the blood-retinal barrier (BRB). This particularly restrictive physiological barrier is important for maintaining the neuroretina as a privileged site in the body by controlling the inflow and outflow of fluid, nutrients, metabolic end products, ions, and proteins. In addition, people with diabetic retinopathy (DR) have been shown to be at increased risk for systemic vascular complications, including subclinical and clinical stroke, coronary heart disease, heart failure, and nephropathy.

Oncoproteomics Technologies
Proteomics continues to forge significant strides in the discovery of essential biological processes, uncovering valuable information on the identity, global protein abundance, protein modifications, proteoform levels, and signal transduction pathways. Cancer is a complicated and heterogeneous disease, and the onset and progression involve multiple dysregulated proteoforms and their downstream signaling pathways. These are modulated by various factors such as molecular, genetic, tissue, cellular, ethnic/racial, socioeconomic status, environmental, and demographic differences that vary with time. The knowledge of cancer has improved the treatment and clinical management; however, the survival rates have not increased significantly, and cancer remains a major cause of mortality. Oncoproteomics studies help to develop and validate proteomics technologies for routine application in clinical laboratories for (1) diagnostic and prognostic categorization of cancer, (2) real-time monitoring of treatment, (3) assessing drug efficacy and toxicity, (4) therapeutic modulations based on the changes with prognosis and drug resistance, and (5) personalized medication. Investigation of tumor-specific proteomic profiles in conjunction with healthy controls provides crucial information in mechanistic studies on tumorigenesis, metastasis, and drug resistance.
