Colony-stimulating factors improve neoadjuvant immunochemotherapy efficacy in non-small-cell lung cancer without EGFR or ALK mutations: A double-center real-world retrospective study.

BACKGROUND: Preclinical evidence suggests colony-stimulating factors (CSFs) may modulate antitumor immunity. This study evaluated granulocyte colony-stimulating factor (G-CSF) administration on neoadjuvant immunochemotherapy (NICT) efficacy in non-small-cell lung cancer (NSCLC) without EGFR or ALK mutations. METHODS: In this double-center retrospective study (2019-2025), 439 stage II/III NSCLC patients without EGFR or ALK mutations receiving NICT followed by R0 resection were analyzed. Propensity score matching (PSM, 1:1) balanced baseline characteristics between G-CSF (n = 135) and control g…

The impact of primary prophylaxis with granulocyte colony-stimulating factors on febrile neutropenia during chemotherapy: a systematic review and meta-analysis of randomized controlled trials.

Eriocalyxin B confers radioprotection of hematopoietic stem and progenitor cells via granulocyte colony-stimulating factor induction.

Ionizing radiation induces injury in multiple organs, particularly in the hematopoietic system; however, the implementation of effective preventive measures for hematopoietic acute radiation syndrome (H-ARS) is still limited. In this study, we investigated the radioprotective effects of a natural diterpenoid, eriocalyxin B (EriB), on hematopoietic injury associated with ARS in mice exposed to total body irradiation (TBI). The results suggested that EriB effectively provides radioprotection against hematopoietic injury, as evidenced by improved survival, increased peripheral blood recovery, and

Granulocyte Colony Stimulating Factor Enhances Decidualization Process of Endometrial Stromal Cells Through STAT3/HOXA10 Axis.

BACKGROUND: Recurrent implantation failure (RIF) is characterized by the repeated failure of implantation, often linked to impaired endometrial receptivity. This study investigates how granulocyte colony-stimulating factor (G-CSF) promotes endometrial stromal cell decidualization. METHODS: THESCs (human telomerase reverse transcriptase-immortalized endometrial stromal cells) were used as an in vitro cell model to induce decidualization. The effects of G-CSF on the expression of decidualization genes and apoptosis during decidualization were examined. Additionally, a chemical inhibitor of sign

Nocardia Infection in Patients With Anti-Granulocyte-Macrophage Colony-Stimulating Factor Autoantibodies: A Prospective Multicenter French Study.

BACKGROUND: Nocardiosis, a bacterial opportunistic infection caused by Nocardia spp, has recently been reported in patients with anti-granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies, but insufficient data are available about disease presentation, outcomes, and occurrence of autoimmune pulmonary alveolar proteinosis (aPAP) in this population. METHODS: We performed a prospective, multicenter, nationwide study in France and included patients with a Nocardia infection who had anti-GM-CSF autoantibodies. We describe their clinical, microbiological, and radiological charact

Aortitis Associated with Prophylactic Short-acting Granulocyte Colony-stimulating Factor Administration: A Case Report and Review of the Literature.

We herein report an 83-year-old woman with filgrastim-associated aortitis during chemotherapy for relapsed diffuse large B-cell lymphoma. She had been treated with filgrastim as a prophylaxis for neutropenia during the fourth cycle of chemotherapy from day 9 to 18. On day 21, she developed a fever. Contrast-enhanced computed tomography revealed aortitis of the descending aorta. The fever abated with non-steroidal anti-inflammatory drug treatment. A literature review identified a small number of aortitis cases all caused by prophylactic use of granulocyte colony-stimulating factors (G-CSFs), am…

A case of granulocyte-colony-stimulating factor-producing gallbladder cancer with lymph node metastasis together with a literature review.

The granulocyte-colony-stimulating factor (G-CSF) glycoprotein stimulates precursor cell proliferation and differentiation in the bone marrow. Various G-CSF-producing tumors have been reported; they showed early progression and an extremely poor prognosis. Here, we report a case of G-CSF-producing gallbladder cancer with lymph node metastasis. In addition, we reviewed 30 previous case reports of G-CSF-producing gallbladder cancers to elucidate the characteristics and most appropriate treatment. During a routine visit to her local doctor for monitoring of diabetes and hypertension, a 68-year-ol

Granulocyte-macrophage colony stimulating factor enhances efficacy of nimustine rendezvousing with temozolomide plus irradiation in patients with glioblastoma.

BACKGROUND: Glioblastoma is the most common and most aggressive type of primary brain tumor. OBJECTIVE: The aim of this study was to investigate the efficacy and safety of intranasal granulocyte-macrophage colony stimulating factor (GM-CSF) administration combined with chemoradiotherapy in patients with glioblastoma who underwent surgery. METHODS: Ninety-two patients were randomly divided into two groups: a control group (n= 46), who received radiotherapy with adjuvant local delivery of nimustine hydrochloride (ACNU) and systemic administration of temozolomide, and an intervention group (n=

Analysis of Granulocyte-Macrophage Colony-Stimulating Factor-Producing T Helper Cells in a Mouse Model of Contact Hypersensitivity.

Parallel to traditional Th1/Th2/Th17/Treg lineages, granulocyte-macrophage colony-stimulating factor-producing T helper (Th-GM) cells have been identified as a distinct subset of T helper cells (GM-CSF+ IFN-γ- IL-17A- IL-22- effector CD4+ T cells) in human and mice. Contact hypersensitivity (CHS) is considered an excellent animal model for allergic contact dermatitis (ACD) in human, manifesting an intact T cell-mediated immune response. To provide a standardized and comprehensive assay to analyze the Th-GM cell subset in the T cell-dependent immune response in vivo, a murine CHS model was indu

Role for Granulocyte Colony-Stimulating Factor in Neutrophilic Extramedullary Myelopoiesis in a Murine Model of Systemic Juvenile Idiopathic Arthritis.

OBJECTIVE: Systemic juvenile idiopathic arthritis (JIA) is a systemic inflammatory disease with childhood onset. Systemic JIA is associated with neutrophilia, including immature granulocytes, potentially driven by the growth factor granulocyte-colony stimulating factor (G-CSF). This study was undertaken to investigate the role of G-CSF in the pathology of systemic JIA. METHODS: Injection of Freund's complete adjuvant (CFA) in BALB/c mice induces mild inflammation and neutrophilia in wild-type (WT) mice and a more pronounced disease, reminiscent to that of JIA patients, in interferon-γ-knockou

Cryptococcus gattii Infection as the Major Clinical Manifestation in Patients with Autoantibodies Against Granulocyte-Macrophage Colony-Stimulating Factor.

PURPOSE: Anti-granulocyte-macrophage colony-stimulating factor autoantibodies (anti-GM-CSF Abs) are a predisposing factor for pulmonary alveolar proteinosis (PAP) and Cryptococcus gattii cryptococcosis. This study aimed to investigate clinical manifestations in anti-GM-CSF Ab-positive patients with C. gattii cryptococcosis and analyze the properties of anti-GM-CSF Abs derived from these patients and patients with PAP. METHODS: Thirty-nine patients diagnosed with cryptococcosis (caused by C. neoformans or C. gattii) and 6 with PAP were enrolled in the present study. Clinical information was ob

Pyoderma Gangrenosum After Total Hip Arthroplasty Associated with Administration of Granulocyte Colony-Stimulating Factor: A Case Report.

CASE: A 69-year-old woman with myelodysplastic syndrome-related pancytopenia was administered granulocyte colony-stimulating factor (G-CSF) before total hip arthroplasty to prevent postoperative infection. One week postoperatively, she developed peri-incisional ecchymosis and associated leukocytosis. Over the next few weeks, surgical site infection was suspected; however, dermatologist evaluation and subsequent biopsy supported a diagnosis of pyoderma gangrenosum, which resolved after prompt steroid administration. CONCLUSION: Postoperative pyoderma gangrenosum should be included in the diffe

Granulocyte Colony-Stimulating Factor Is Safe and Well Tolerated following Allogeneic Transplantation in Patients with Sickle Cell Disease.

Granulocyte colony-stimulating factor (G-CSF) used after hematopoietic stem cell transplantation (HSCT) can enhance neutrophil recovery in patients rendered neutropenic by the preparative regimen. G-CSF is contraindicated in patients with sickle cell disease (SCD), because life-threatening complications can ensue in the presence of sickle vasculopathy. The safety profile of G-CSF after HSCT for SCD has not been described, however. We report clinical outcomes in the first 100 days post-HSCT in 62 patients supported with G-CSF until neutrophil recovery on a clinical trial of reduced- intensity c

The Presence of Colony-Stimulating Factor-1 and Its Receptor in Different Cells of the Testis; It Involved in the Development of Spermatogenesis In Vitro.

Spermatogenesis is a complex process, in which spermatogonial cells proliferate and differentiate in the seminiferous tubules of the testis to generate sperm. This process is under the regulation of endocrine and testicular paracrine/autocrine factors. In the present study, we demonstrated that colony stimulating factor-1 (CSF-1) is produced by mouse testicular macrophages, Leydig, Sertoli, peritubular cells and spermatogonial cells (such as CDH1-positively stained cells; a marker of spermatogonial cells). In addition, we demonstrated the presence of CSF-1 and its receptor (CSF-1R) in testicul

[Emergence of mutation in the colony-stimulating factor 3 receptor gene during follow-up of unclassifiable myeloproliferative neoplasm].

A 25-year-old male with a medical history of stress polycythemia was admitted to a previous hospital for leukocytosis, anemia, and thrombocytopenia. Bone marrow examination revealed left-shifted myeloid hyperplasia without increased blasts and normal male karyotype. No mutations of JAK2, V617F, and colony-stimulating factor 3 receptor gene (CSF3R) were detected. Fluorescence in-situ hybridization for BCR-ABL1 and FIP1L1-PDGFRA were negative. Based on these findings, a diagnosis of an unclassifiable myeloproliferative neoplasm was made, and he was started on hydroxyurea treatment. He was referr

Clinical significance of serum anti-granulocyte-macrophage colony-stimulating factor autoantibodies in patients with sarcoidosis and hypersensitivity pneumonitis.

BACKGROUND: Anti-granulocyte-macrophage colony-stimulating factor autoantibody (GMAb) has been recognized as a diagnostic biomarker for autoimmune pulmonary alveolar proteinosis (aPAP). The aims of this study were to know the incidence of increased level of serum GMAb in granulomatous lung diseases (sarcoidosis and hypersensitivity pneumonitis [HP]) and to clarify the role of GMAb. Consecutive individuals diagnosed with sarcoidosis (n = 92) and HP (n = 45) at National Hospital Organization Kinki-Chuo Chest Medical Center were retrospectively analyzed. We measured serum GMAb levels at the diagn

GM-CSF (granulocyte macrophage colony-stimulating factor) supplementation in culture media for women undergoing assisted reproduction.

BACKGROUND: GM-CSF (granulocyte macrophage colony-stimulating factor) is a growth factor that is used to supplement culture media in an effort to improve clinical outcomes for those undergoing assisted reproduction. It is worth noting that the use of GM-CSF-supplemented culture media often adds a further cost to the price of an in vitro fertilisation (IVF) cycle. The purpose of this review was to assess the available evidence from randomised controlled trials (RCTs) on the effectiveness and safety of GM-CSF-supplemented culture media. OBJECTIVES: To assess the effectiveness and safety of GM-C

Granulocyte-Colony Stimulating Factor Reduces Cocaine-Seeking and Downregulates Glutamatergic Synaptic Proteins in Medial Prefrontal Cortex.

Psychostimulant use disorder is a major public health issue, and despite the scope of the problem there are currently no Food and Drug Administration (FDA)-approved treatments. There would be tremendous utility in development of a treatment that could help patients both achieve and maintain abstinence. Previous work from our group has identified granulocyte-colony stimulating factor (G-CSF) as a neuroactive cytokine that alters behavioral response to cocaine, increases synaptic dopamine release, and enhances cognitive flexibility. Here, we investigate the role of G-CSF in affecting extinction

Expression of granulocyte macrophage-colony stimulating factor and its receptor in the synovium of osteoarthritis patients is negatively correlated with pain.

OBJECTIVES: The crosstalk between the immune and nervous system in the regulation of OA pain is increasingly becoming evident. GM-CSF signals in both systems and might be a new treatment target to control OA pain. Anti GM-CSF treatment has analgesic effects in OA without affecting synovitis scores, suggesting that treatment effects are not caused by local anti-inflammatory effects. We aimed to evaluate whether expression of GM-CSF and its receptor GM-CSFrα in synovial tissue is linked to synovial inflammation and/or knee pain in knee OA patients. METHODS: Cartilage and synovial tissue of knee

Association of plasma macrophage colony-stimulating factor with cardiovascular morbidity and all-cause mortality in chronic hemodialysis patients.

BACKGROUND: Cardiovascular disease (CVD) events are the main cause of death in long-term hemodialysis (HD) patients. Macrophage colony- stimulating factor (M-CSF) is actively involved in the formation of atherosclerosis and causes plaque instability, thrombosis and the development of acute coronary syndromes. However, little information is available on the role of M-CSF in HD patients. We aimed to investigate the association between plasma M-CSF levels and CVD events as well as all-cause mortality in patients undergoing long-term HD. METHODS: Fifty two HD patients and 8 healthy controls were
