Pathogen effector disarms circadian-immune crosstalk by targeting TCP14, a dual regulator of clock and defense
Wang et al. identify the transcription factor TCP14 as a critical nexus linking the circadian clock and plant defense. The study reveals how the pathogen effector HaRxL21 hijacks this connection by recruiting TPL/TPR1 repressors to disarm TCP14, thereby providing a mechanistic understanding of how pathogens overcome circadian-gated immunity.
Evaluation of Pirfenidone for the Treatment of Acute Respiratory Distress Syndrome A Case Report
【Evaluation of Pirfenidone for the Treatment of Acute Respiratory Distress Syndrome: A Case Report】 Full article: (Authored by Carlie Cressey Brown, et al., from University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences (USA), etc.)
Acute respiratory distress syndrome (ARDS) is an acute hypoxemic lung injury typically caused by a predisposing factor such as infection, aspiration, transfusion or shock. While accepted management includes lung protective ventilation strategies, there is currently no mainstay pharmacologic treatment for ARDS. Due to its anti-inflammatory, antioxidant, and antifibrotic properties, pirfenidone presents as a potential therapeutic option for patients with ARDS. This paper presents a case of a patient with ARDS secondary to pneumonia who was refractory to standard therapies and effectively treated with pirfenidone.
Background: Acute respiratory distress syndrome (ARDS) is an aggressive, inflammatory lung injury with a high mortality rate. While accepted management includes lung protective ventilation strategies, there is currently no mainstay pharmacologic treatment for ARDS. Adjunctive pharmacologic treatment may include glucocorticoids, neuromuscular blockade and inhaled pulmonary vasodilators. Due to its anti-inflammatory, antioxidant, and antifibrotic properties, pirfenidone presents as a potential therapeutic option for patients with ARDS. Case Report: We present a patient treated with pirfenidone for ARDS. Our patient was a 31-year-old man who presented to the hospital with dyspnea on exertion and concern for relapsed acute myeloid leukemia. After a complex hospital course, the off-label use of pirfenidone 801 mg three times daily was pursued to treat his ARDS. The patient’s ARDS resolved after 10 days of pirfenidone, with no adverse effects, and he was discharged. Conclusions: This case illustrates the potential utility of pirfenidone in the management of ARDS. After no improvement with widely accepted strategies including lung protective ventilation and steroids, the patient demonstrated recovery after the initiation of pirfenidone. We can infer correlation but not causation in this setting, prompting the need for further prospective randomized clinical trials to establish pirfenidone as a therapeutic option in ARDS.
Cardiopathogenic T Cells Govern Progression and Functional Remodeling in Inflammatory Cardiomyopathy and Chronic Myocarditis
In this JACCBTS article, Joachimbauer et al. demonstrate that cardiopathogenic CD4+ T cells induce acute yet reversible inflammation-driven myocardial changes, and that the persistence of these cells is a key factor driving functional cardiac remodeling.

Nanohydrogels steer cancer drugs to tumors, aiming to spare healthy tissue
Exhaustion creeps in. Appetite vanishes. Hair thins. The person in the mirror looks gaunt. It’s the paradox of cancer treatment: The same drugs meant to save a life can also wear the body down. Nick Housley, assistant professor in Georgia Tech’s School of Biological Sciences, wants to change that. He studies where cancer drugs go once they’re inside the body, including places they were never intended to reach. Some of the medicine finds the tumor. The rest interacts with healthy tissue.
This approach has saved millions of lives. It can also create punishing side effects. “The problem isn’t that these drugs don’t work,” said Housley. “It’s that they affect far more of the body than they need to.”

Cardiovascular benefits of obesity therapies: an overview of obesity medicines and metabolic bariatric surgery
Obesity is an independent driver of cardiovascular disease (CVD), mediated through adverse haemodynamic loading, insulin resistance, systemic inflammation, endothelial dysfunction and prothrombotic pathways. Contemporary obesity therapies show cardiovascular (CV) benefits beyond improvements in traditional risk factors. Across large CV outcome trials, glucagon-like peptide 1 receptor agonists consistently reduce three-point major adverse CV events (MACE) in patients with overweight, obesity and established CVD with and without diabetes. In obesity-related heart failure of preserved ejection fraction, semaglutide and tirzepatide improve symptoms and functional capacity and reduce worsening heart failure events, while effects on CV mortality remain uncertain.

Deep AI training gets more stable by predicting its own errors
Artificial intelligence now plays Go, paints pictures, and even converses like a human. However, there remains a decisive difference: AI requires far more electricity than the human brain to operate. Scientists have long asked the question, “How can the brain learn so intelligently using so little energy?” KAIST researchers have moved one step closer to the answer.
A research team led by Distinguished Professor Sang Wan Lee of the Department of Brain and Cognitive Sciences has developed a new technology that applies the learning principles of the human brain to deep learning, enabling stable training even in deep artificial intelligence models.
Our brain does not passively receive the world. Instead of merely perceiving what is happening in the present, it first predicts what will happen next and, when reality differs from that prediction, adjusts itself to reduce the difference (i.e., prediction error). This is similar to anticipating an opponent’s next move in Go and changing strategy if the prediction turns out to be wrong. This mode of information processing is known as “Predictive Coding.”
DNA barcoding reveals which gene-therapy nanoparticles reach targets in vivo
Drug delivery researchers have vastly improved the potential of genetic therapies by overcoming the challenge of consistently getting genes and gene-editing tools where they need to be within cells. Findings of the study spearheaded by Oregon State University College of Pharmacy graduate student Antony Jozić are published in Nature Biotechnology.
When gene therapies enter a cell, they are often sent to lysosomes, the cell’s trash and recycling centers, where therapeutic genetic material is broken down before it can work. For gene therapies to succeed, they must avoid disposal and reach the part of the cell where they can function.
