THC não tem "a mesma estrutura do estrógeno" e nem se liga aos receptores estrogênicos ERα ou ERβ , ele se liga aos receptores canabinoides cb1 e cb2 do sistema endocanabinoide...

Perso j'aime pas le termes neo cannabinoides il englobe les semi-synthé et synthétique alors que chimiquement ça n'a rien a voir, il n'existe pas de semi-synthé qui sont agoniste complets/sélectifs des récepteurs cb1 et cb2 comparé a ceux synthétique et le risque nest pas moindre

**Endometriosis and migraines are increasingly viewed through the lens of endocannabinoid dysregulation or clinical endocannabinoid deficiency (CECD/CED), where impaired endocannabinoid system (ECS) signaling contributes to chronic pain, inflammation, immune dysfunction, and related symptoms.** This unifying framework highlights how reduced effective ECS tone—due to altered ligand levels, receptor expression, or enzyme activity—underlies key pathological processes in both conditions. ### Endocannabinoid System (ECS) Overview The ECS is a lipid-based signaling network that promotes homeostasis by modulating pain, inflammation, immune responses, neurotransmission, vascular tone, cell proliferation/apoptosis, and reproductive functions. It includes: - **Cannabinoid receptors** (primarily CB1 in nervous and reproductive tissues; CB2 in immune cells).- **Endocannabinoids** like anandamide (AEA) and 2-arachidonoylglycerol (2-AG), produced on-demand. - **Enzymes** for synthesis and breakdown (e.g., FAAH, MAGL). Dysregulation disrupts this balance, leading to heightened nociception, persistent inflammation, and tissue abnormalities. ### Endometriosis as ECS Dysregulation Endometriosis features ectopic endometrial-like tissue that drives chronic inflammation, pelvic pain, dysmenorrhea, and infertility. Research consistently shows ECS alterations: - **Receptor changes**: Decreased CB1 expression in endometrial tissue, stromal cells, and lesions impairs anti-inflammatory and analgesic signaling. Variable CB2 shifts and upregulated TRPV1 (pro-nociceptive) are also noted. - **Ligand and enzyme dynamics**: Often elevated AEA/2-AG in plasma/peritoneal fluid (correlating with pain), yet reduced PEA and overall signaling efficiency due to fewer receptors. This creates a "paradox" of compensatory overproduction amid functional deficiency. Lower synthesis/degradation enzymes in lesions further contribute. - **Pathophysiological roles**: The ECS regulates lesion establishment (migration, proliferation, angiogenesis, apoptosis resistance) and immune modulation (e.g., mast cells, cytokines). Dysregulation promotes survival of ectopic tissue in estrogen-rich inflammatory environments and exacerbates pain via central/peripheral sensitization. Key papers include: - "The Clinical Significance of Endocannabinoids in Endometriosis" (2017): pmc.ncbi.nlm.nih.gov/article… - "Role of the endocannabinoid system in the pathophysiology of endometriosis" (2022): link.springer.com/article/10… - "Endocannabinoids and their receptors modulate endometriosis pathogenesis and immune response" (2024): elifesciences.org/articles/9… - Review on understanding the ECS in endometriosis: endonews.com/understanding-e… Some researchers explicitly describe endometriosis as fitting an endocannabinoid deficiency profile. ### Migraines and CECD Migraines involve neurovascular inflammation, often comorbid with endometriosis (shared menstrual triggers, higher prevalence, overlapping conditions like IBS/fibromyalgia). - **Evidence**: Lower AEA in cerebrospinal fluid/plasma of migraine patients; altered FAAH activity; reduced ECS tone linked to trigeminovascular sensitization, CGRP release, and cortical spreading depression. - **Mechanisms**: ECS normally dampens serotonin dysregulation, neuroinflammation, and pain thresholds. Deficiency lowers the migraine threshold. Foundational work by Ethan Russo positions migraines (with fibromyalgia/IBS) as core CECD examples: - "Clinical Endocannabinoid Deficiency (CECD)" (2004): pubmed.ncbi.nlm.nih.gov/1515… - "Clinical Endocannabinoid Deficiency Reconsidered" (2016): pubmed.ncbi.nlm.nih.gov/2886… (full text often available via PMC) - Additional support: "Emerging Role of (Endo)Cannabinoids in Migraine" (2018): pubmed.ncbi.nlm.nih.gov/2974… ### Shared Spectrum and Comorbidity Both conditions exhibit hormonal-ECS interactions (estrogen modulates ECS components), central sensitization, and inflammatory/immune dysregulation. Higher comorbidity rates suggest a common ECS

**Cannabidiol (CBD) Exhibits Dose-Dependent Anti-Cancer Effects Across Multiple Cancer Types** Research demonstrates that cannabidiol (CBD) consistently produces dose-dependent reductions in cancer cell viability, proliferation, migration, invasion, and tumor growth while inducing apoptosis and cell cycle arrest in various preclinical models. Below is a compilation of key studies highlighting these effects across different cancers, with specific dose ranges and outcomes. ### Breast Cancer **CBD Induces Concentration-Dependent Apoptosis and Reduces Viability in Breast Cancer Cell Lines** CBD treatment (0–10 μM for 24 hours) significantly decreased cell viability in both estrogen receptor-positive (e.g., MCF-7, T-47D) and triple-negative (e.g., MDA-MB-231) breast cancer lines in a concentration-dependent manner. It triggered apoptosis (measured by Annexin V staining) and inhibited survival pathways independently of CB1/CB2 receptors at lower doses, with partial CB2 involvement at higher concentrations. Higher doses enhanced pro-apoptotic proteins like p53, Caspase-3, and Bax. **CBD and THC Mixture Shows Dose- and Time-Dependent Anti-Proliferative and Pro-Apoptotic Effects in Breast Cancer** In MDA-MB-231 and MCF-7 cells, CBD/THC (3:1 ratio, 12.5–17.5 μg/mL) inhibited proliferation dose- and time-dependently over 24–48 hours, reducing viability by up to 86% at higher doses. It increased apoptotic cells (Annexin V/PI staining) and altered cell cycle progression, with stronger effects in triple-negative lines. ### Colorectal Cancer **CBD Represses Viability and Induces G1 Arrest and Apoptosis in Colorectal Cancer Cells** CBD (0–40 μM for 24–48 hours) reduced viability in multiple human colorectal cancer lines (e.g., HCT116, SW480) in a dose-dependent manner, with IC50 values ranging from 4.7–20 μM. It caused G1-phase cell cycle arrest, elevated apoptosis markers, and endoplasmic reticulum stress. **CBD Reduces Viability and Enhances Apoptosis in p53-Dependent Colorectal Cancer Models** In HCT116 (p53 wild-type and knockout) and other lines, CBD (5–20 μM for 24–48 hours) lowered viability dose-dependently (IC50 7.9–24.3 μM). Sensitivity was higher in p53 wild-type cells, with increased ROS, mitochondrial disruption, and caspase activation at higher doses. ### Glioma/Glioblastoma **CBD Is Cytotoxic and Perturbs Mitochondrial Function in Glioma Cells** CBD (0–20 μg/mL for 96 hours) inhibited proliferation and induced cytotoxicity in human (U87MG, U373MG) and canine glioma lines in a dose-dependent manner (IC50 4.9–8.2 μg/mL). It reduced oxygen consumption and ATP production dose-dependently within 2 hours, leading to swollen mitochondria and apoptosis (rescued by apoptosis inhibitors). **CBD Suppresses Glioma Cell Viability in Combination Contexts** CBD and BCNU each produced dose-dependent suppression of T98G glioma cell viability, with CBD enhancing overall anti-tumor activity through apoptotic pathways. ### Prostate Cancer **CBD Decreases Viability and Induces Apoptotic Cell Death in Prostate Cancer Cells** In PC3 cells, CBD (0.03–10 μM for 48 hours) reduced viability dose-dependently (up to 37% at higher doses) and activated caspase-3/7 pathways, increasing DNA fragmentation, ROS, and pro-apoptotic Bax while altering mitochondrial potential. ### Lung Cancer and Other Solid Tumors **CBD Inhibits Long-Term Survival in Multiple Cancer Cell Lines Including Lung Carcinoma** CBD showed dose-dependent killing in large cell lung carcinoma (H460, IC50 8.47 μM), metastatic breast (MDA-MB-231, IC50 8.35 μM), melanoma (A375, IC50 2.45 μM), cervical carcinoma, and osteosarcoma lines after 7–10 days. Apoptosis was confirmed via PARP cleavage, with ER stress as a key mechanism. **CBD Reduces Proliferation, Migration, and Invasion in Head and Neck Squamous Cell Carcinoma** CBD treatment decreased HNSCC cell viability, migration, and invasion dose- and t

【CBGはなぜ「日中向き」と言われるのか?】 CBGは「明るくなる」「集中できる」「頭が整う」と口コミやレビューでよく見れますが、実はCB1・CB2受容体への作用はかなり弱いです。 それでも体感が語られる理由は、CBGが“その他の受容体”に強く働きかける可能性にあります。 ① α-2アドレナリン受容体(α2AR) CBGはこの受容体に非常に強く作用するとされています。α2ARは血圧を下げ、交感神経の過剰な興奮を抑える働きがあり、「落ち着きながら集中できる」「ノイズが減る」感覚に関与している可能性があります。 ② セロトニン5-HT1A受容体 CBGはこの受容体の強力な拮抗薬(ブロッカー)として作用。その結果、間接的に ・セロトニン(安心感・幸福感) ・ノルアドレナリン(覚醒・集中) ・ドーパミン(やる気・モチベーション) が増える可能性が示唆されています。 ③ PPAR(ペルオキシソーム増殖因子活性化受容体) 代謝・炎症・脂質や糖の調整に関与する受容体。 CBGはこの受容体への親和性も高く、メタボや代謝系への可能性も研究されています。 CBGは「この受容体=この効果」と断定できる段階ではありません。しかし、これらの受容体作用を総合するとCBGが「日中向き」「集中・覚醒・安定感がある」と言われる理由は、決して根拠のない噂ではないことが見えてきます。 CBGは、神経調節・集中・気分・代謝まで幅広い可能性を持つカンナビノイド。今後の研究がさらに期待される成分です。
