CHI3L1 в Множественном склерозе-от скамьи до клиники.

Множественный склероз (MS) — хроническое демиелинирующее заболевание центральной нервной системы (CNS) с сложным и не вполне понятным этиопатологическим фоном, предусматривающим воспалительные и нейродегенеративные процессы. CHI3L1 был замешан в таких патологических условиях, как воспаление, повреждение и нейродегенерация, и, вероятно, будет играть определенную роль в физиологическом развитии CNS. CHI3L1 производится главным образом макрофагами CNS, микроглией и активированными астроцитами. Структура выражения CHI3L1 при поражениях MS может поддержать важную роль астроцитов в модуляции подстре

Curcumin as a promising therapeutic agent for diabetic neuropathy: from molecular mechanisms to functional recovery.

Diabetes mellitus is an endocrine disorder characterized by prolonged hyperglycemia. It results from either insulin deficiency (type 1 diabetes mellitus, T1DM) or insulin resistance (type 2 diabetes mellitus, T2DM). This condition has emerged as a significant health concern in recent years. Hyperglycemia induces the overproduction of reactive oxygen species (ROS), which can modulate multiple pathways, including AGEs-RAGE, PKC stimulation, NF-κB and PI3K/AKT. These pathways contribute to diabetes-related complications such as inflammation, oxidative stress, insulin resistance, and reduced gluco

Cellular senescence-from solid organs to vascularized composite allotransplants.

Vascularized composite allotransplantation (VCA) has emerged as a novel therapy approach to restore form and function in patients with severe tissue defects of the face, hand, and abdominal wall, among other anatomical regions. The composite allografts comprise different tissues such as skin, muscle, or bone. Clinical data demonstrate promising mid- and long-term outcomes following VCA surgery, but our understanding of the cellular interactions and molecular pathways in VCA surgery is oftentimes deduced from solid organ transplantation (SOT). In SOT, the concept of cellular senescence has grow

МикроРН в связи с иммунными заболеваниями: механизм, функции и терапевтические аспекты.

МикроРНК (миРНК) представляют собой эволюционно сохранившиеся, некодирующие молекулы РНК приблизительно 18-25 нуклеотидов по длине, которые регулируют генное выражение на посттранарном уровне. Их главным механизмом действий является пост-ранарное заглушение генов с помощью интерференции РНК, которое достигается путем привязки к дополнительным последовательности в рамках целевых посыльных РНК (mRNA). Накопляемые данные свидетельствуют о ключевой роли miRNA в развитии, дифференциации и функционировании иммунных клеток, а также в сохранении иммунной гомеостазии. Более полное понимание сложных мол

Mechanisms of spinal glial activation in chemotherapy-induced peripheral neuropathy: Focus on microglia and astrocytes.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common complication in patients with malignant tumors during chemotherapy. The pathological mechanisms of CIPN remain unclear, and effective preventive and therapeutic strategies are still lacking, posing a major challenge in clinical practice. Aberrant activation of spinal glial cells, particularly microglia and astrocytes, is a key pathological hallmark of CIPN. Evidence from multiple animal models supports a causal link between glial activation and CIPN, suggesting that glial cells may serve as potential therapeutic targets. However, ow

Mesenchymal stem cell transplantation plays a role in relieving cancer pain.

Tumors can invade, compress, and damage nerves, leading to persistent pain and seriously affecting the quality of life of patients. However, their treatment is challenging. Sensitization of peripheral receptors, abnormal activity of primary sensory neurons, activation of glial cells, enhanced inflammatory responses, and sensory information transmission contribute towards cancer pain. Therefore, considerable attention has been paid to exploring prospective methods to inhibit the occurrence of these factors and relieve cancer pain. Studies on different types of pains have revealed that the trans

Purinergic Signalling: Therapeutic Developments.

Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990's when receptor subtypes for purines and pyrimidines were cloned and characterised, which includes four subtypes of the P1 (adenosine) receptor, seven subtypes of P2X ion channel receptors and 8 subtypes of the P2Y G protein-coupled receptor. Early studies were largely concerned with the physiology, pharmacology and biochemistry of purinergic signalling. More recently, the focus has been on the pathophysiology and the

Role of Nanomedicine-Based Therapeutics in the Treatment of CNS Disorders.
