The Role of the CCR5 Receptor in Neuropathic Pain Modulation: Current Insights and Therapeutic Implications.

Neuropathic pain, a chronic condition arising from injury or dysfunction of the somatosensory nervous system, is characterized by persistent hypersensitivity and spontaneous pain. The chemokine receptor CCR5 (C-C motif chemokine receptor 5) has recently been identified as a critical mediator in neuroinflammation and neuropathic pain signaling pathways. Expressed on immune cells and neurons, CCR5 regulates immune cell recruitment and activation, thereby contributing to neuronal sensitization and maintenance of pain states. This review examines the currently characterized molecular mechanisms th

Pomalidomide mitigates neuronal loss, neuroinflammation, and behavioral impairments induced by traumatic brain injury in rat.

BACKGROUND: Traumatic brain injury (TBI) is a global health concern that typically causes emotional disturbances and cognitive dysfunction. Secondary pathologies following TBI may be associated with chronic neurodegenerative disorders and an enhanced likelihood of developing dementia-like disease in later life. There are currently no approved drugs for mitigating the acute or chronic effects of TBI. METHODS: The effects of the drug pomalidomide (Pom), an FDA-approved immunomodulatory agent, were evaluated in a rat model of moderate to severe TBI induced by controlled cortical impact. Post-TBI

Острый панкреатит в качестве первоначального представления метастатического рака груди, вызванного злокачественной гиперкальцемией: доклад по делу.

Острый панкреатит, вызванный гиперкальцемией, является редким заболеванием, которое чаще всего ассоциируется с первичным гиперпаратироидизмом или продвинутыми магнеями, и представляет собой экстренную метаболическую ситуацию. Мы сообщаем о случае 63-year-old Женщина, которая испытывала сильную эпигазную боль в животе, запор и приступы дезориентации. Лабораторные тесты выявили повышенные поджелудочные ферменты и сильную гиперкальцемию. Был диагностирован острейший панкреатит, вторичный до гиперкальцемии, и нормальные уровни паратироидного гормона (PTH) исключали первичный гиперпаратироидизм. Пр

Safety and effects of two mistletoe preparations on production of Interleukin-6 and other immune parameters - a placebo controlled clinical trial in healthy subjects.

BackgroundIn Germany, Iscucin® Populi (IP), a preparation from mistletoe growing on the poplar tree, is used in cancer therapy while Viscum Mali e planta tota (VM), a preparation from mistletoe growing on the apple tree, is used in patients with osteoarthritis. Since mistletoe preparations are suspected to induce production of potentially tumor promoting cytokines like interleukin (IL)-6, further studies on the immunological effects are of interest.MethodsIn this 3-armed randomized, double blind clinical trial healthy volunteers received increasing doses of either IP (strength F, 0.0125%, G, 0

The EPICURE study: a pilot prospective cohort study of heterogeneous and massive data integration in metastatic breast cancer patients.

BackgroundBreast cancer is the most common cancer in women and the first cancer concerning mortality. Metastatic breast cancer remains a disease with a poor prognosis and about 30% of women diagnosed with an early stage will have a secondary progression. Metastatic breast cancer is an incurable disease despite significant therapeutic advances in both supportive cares and targeted specific therapies. In the management of a metastatic patient, each clinician follows a highly complex and strictly personal decision making process. It is based on a number of objective and subjective parameters whic

Mantle Cell Lymphoma Presenting as Acute Abdominal Syndrome: A Rare Case Report and Literature Review.

BACKGROUND: Acute abdominal syndrome can be caused by several possible reasons. The most common causes are perforation of a gastroduodenal ulcer, peritonitis, intestinal obstructions, and perforation of an appendix or fallopian tube. Fever and pain can be caused by an appendicitis or sigmoiditis. Appendiceal lymphoma is a rare disease that is usually found incidentally during appendectomy. Most of the cases are non-Hodgkin's lymphomas. Mantle cell lymphoma is an aggressive B-cell non-Hodgkin's lymphoma with a poorer prognosis than other B-cell lymphomas; thus, a definitive diagnosis is essenti

T-Type Calcium Channels: A Mixed Blessing.

The role of T-type calcium channels is well established in excitable cells, where they preside over action potential generation, automaticity, and firing. They also contribute to intracellular calcium signaling, cell cycle progression, and cell fate; and, in this sense, they emerge as key regulators also in non-excitable cells. In particular, their expression may be considered a prognostic factor in cancer. Almost all cancer cells express T-type calcium channels to the point that it has been considered a pharmacological target; but, as the drugs used to reduce their expression are not complete

Targeting the NLRP3 inflammasome in kidney disease: molecular mechanisms, pathogenic roles, and emerging small-molecule therapeutics.

Inflammatory responses represent a core pathological process driving the progression of both acute and chronic kidney diseases. As a key effector of the innate immune system, the NLRP3 inflammasome is widely activated in renal resident cellsand infiltrating immune cells, positioning it as a critical nexus linking metabolic dysregulation, cellular stress, and tissue injury. Accumulating preclinical and clinical evidence in recent years demonstrates that aberrant activation of the NLRP3 inflammasome directly promotes glomerular damage, tubulointerstitial inflammation, fibrosis, and vascular dysf

Antitumoral Effects of Tricyclic Antidepressants: Beyond Neuropathic Pain Treatment.

Growing evidence shows that nerves play an active role in cancer development and progression by altering crucial molecular pathways and cell functions. Conversely, the use of neurotropic drugs, such as tricyclic antidepressants (TCAs), may modulate these molecular signals with a therapeutic purpose based on a direct antitumoral effect and beyond the TCA use to treat neuropathic pain in oncology patients. In this review, we discuss the TCAs' safety and their central effects against neuropathic pain in cancer, and the antitumoral effects of TCAs in in vitro and preclinical studies, as well as in
