A Daily Injection Paradigm Disrupts the Environmental-Enrichment-Induced Pruning of Miswired Axonal Projections in Developing Mice. (PubMed, Dev Neurobiol) - "Aiming to confirm a causal role for microglial-mediated engulfment in this process, we assessed the effect of daily injections of minocycline or vehicle saline from P18 to P24 (inclusive) on measures of microglial reactivity and anatomical corrective pruning in P25 Ten-m3 KO mice...This suggests that the injection procedure itself disrupted the experience-induced microglial-mediated circuit repair. These results underscore the highly sensitive nature of EE-driven corrective pruning actions of microglia and the critical importance of considering and controlling for all aspects of experience."

Geographic shift of Japanese spotted fever and diagnostic overshadowing by COVID-19 testing: A genetically confirmed northernmost case. (PubMed, IDCases) - "Physical examination revealed a diffuse rash and an eschar on the lower leg. Rickettsial infection was suspected, and intravenous minocycline was initiated. Rickettsia japonica was later confirmed by PCR and serology. This case represents the northernmost genetically confirmed JSF in Japan and emphasizes the importance of maintaining a broad differential diagnosis, particularly when COVID-19 test results conflict with clinical findings."

Refractory chronic seroma following latissimus dorsi flap breast reconstruction successfully treated by surgical excision: A case report. (PubMed, JPRAS Open) - "We report a case of a refractory seroma that developed in the early postoperative period and persisted for over four years despite 79 aspirations (including 37 combined with corticosteroid injections and 5 minocycline sclerotherapy sessions)...This case highlights the importance of early recognition and surgical consideration in managing chronic seromas unresponsive to conservative therapy. Surgical excision combined with compression may achieve excellent long-term outcomes and improve patient quality of life."

Cost-Effectiveness of Minocycline Intravenous for the Treatment of Serious Infections Due to Multidrug-Resistant Acinetobacter baumannii in Jordan (ISPOR-EU 2025) - "This study assesses the cost-effectiveness of IV minocycline versus IV colistin in treating MDR A. baumannii infections in Jordan. A 28-day decision-tree model was developed to evaluate the cost-effectiveness of IV minocycline compared to IV colistin for the treatment of MDR Acinetobacter baumannii infections from a Jordanian payer perspective. IV minocycline is a dominant treatment option for MDR A. baumannii infections in Jordan. These findings may support clinicians and healthcare decision-makers in prescribing cost-effective therapies, contributing to more efficient allocation of healthcare resources."

THE CLEARANCE OF NEUTROPHIL EXTRACELLULAR TRAPS BY CONSTRAINT-INDUCED MOVEMENT THERAPY DEPENDS ON MICROGLIA (WSC 2025) - "The purpose of this study is to determine whether the clearance effect of CIMT on NETs is related to microglia and its specific mechanism. Administration of the Colony-stimulating factor 1 receptor inhibitor PLX3397 and intraperitoneal injection of minocycline were used to deplete and inactivate microglia, respectively. CIMT mediates the phagocytosis of NETs by microglia in ischemic cortex and is beneficial to maintain the balance of pro-inflammatory/anti-inflammatory microglia. The synaptic budding is at least partially attributed to the spatial location provided by microglial phagocytosis of NETs. IL-33/ST2 may be the target mediating this phagocytosis."

ANTIMICROBIAL-RESISTANT GRAM-NEGATIVE INFECTIONS IN THE INTENSIVE CARE UNIT (CHEST 2025) - "He was treated with broad spectrum intravenous (IV) antibiotics with Vancomycin and Cefepime...He was started on IV ceftazidime-avibactam (Avycaz) and Infectious Disease (ID) was consulted...The patient was treated with high dose IV ampicillin-sulbactam 9 g every 8 hours along with IV Minocycline 200mg BID for 5 days... In patients with a history of colonization with MDRO, it is important to evaluate the patient thoroughly before treating the infection. Consequences to early treatment may be the rise of more resistant bugs whereas a delay or no treatment can lead to further deterioration of the patient."

Scrub Typhus With an Unknown Source of Infection. (PubMed, Cureus) - "She was treated with intravenous minocycline for 14 days, following which the fever resolved and laboratory abnormalities improved...Her clinical course was favorable, and she was discharged in good condition. Although scrub typhus is traditionally associated with rural environments, urban transmission is becoming more recognized, possibly due to ecological changes such as urban heat islands, where temperatures are higher than in surrounding rural areas, potentially expanding the habitats of vector mites. This case highlights that scrub typhus should be considered in patients presenting with fever, rash, and eschar, even when no clear environmental exposure is identified."

Minocycline prevents monocrotaline-induced pulmonary hypertension through the attenuation of endothelial dysfunction and vascular wall thickening. (PubMed, J Pharmacol Sci) - "PH-preventing effect of minocycline does not seem to be mediated via the actions on matrix metalloproteinase, inflammatory cytokines, and mast cells migration in lung. In summary, we revealed for the first time that minocycline ameliorated the MCT-induced PH in rats, at least partly through preventing pulmonary artery endothelial dysfunction and wall thickening."

Administration of Corticosteroids for Prompt Suppression of Cytokine Storm in Severe Cases of Japanese Spotted Fever. (PubMed, Cureus) - "Early treatment with tetracycline antibiotics is crucial to prevent severe complications, such as pneumonia, meningitis, disseminated intravascular coagulation (DIC), and systemic inflammatory response syndrome...Initial treatment with ceftriaxone was ineffective, leading to a switch to intravenous minocycline and levofloxacin. Considering the high levels of C-reactive protein, procalcitonin, ferritin, and soluble interleukin-2 receptor, intravenous hydrocortisone (200 mg/day) was administered to control the cytokine storm...Early administration of corticosteroids along with antibiotics effectively suppressed the cytokine storm in this case. Reports have shown mixed results, indicating the need for further research to determine the optimal type, dosage, and duration of corticosteroid treatment."

A potential mechanism clue to the periodic storm from microglia activation and progressive neuron damage induced by paraquat exposure. (PubMed, Environ Toxicol) - "Surprisingly, the injection of minocycline before PQ for many hours not only can effectively improve the neurobehavioral symptoms of mice but inhibit the activation of microglia and the release of pro-inflammatory substances, even controlling the gradual damage and loss of neurons. A further mechanism of minocycline hampered the expression levels of key signaling proteins PI3K, PDK1, p-AKT, and CD11b (the receptor of microglia membrane recognition), while a large number of inflammatory factors. Our results suggested that the CD11b/PI3K/NOX2 pathway may be a clue that microglia-mediated inflammatory responses and neuronal damage in a PQ-induced abnormal behavior Parkinson-like mouse."

Minocycline protects against microgliopathy in a Csf1r haplo-insufficient mouse model of adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP). (PubMed, J Neuroinflammation) - "Our study shows that CSF1R deficiency results in aberrant microglial activation, characterized by a pro-inflammatory phenotype and enhanced phagocytosis of myelin. Our results also indicate that microglial inhibition by minocycline can ameliorate behavioral impairment and ALSP pathogenesis in CSF1R-deficient male mice, suggesting a potential therapeutic target for CSF1R-related leukoencephalopathy. Collectively, these data support that minocycline confers protective effects against CSF1R-related microgliopathy in male ALSP model mice."
