The Homo sapiens charged multivesicular body protein 5 (CHMP5) is a member of the multivesicular body, which serves as an anti-apoptotic protein and is thought to participate in leukemogenesis. In this study, a short-hairpin RNA-based RNA interference approach was used to inhibit the expression of CHMP5 in the leukemic cell line U937. After CHMP5 was inhibited, antibody microarray and western blot analysis were used to study the changes in the programmed cell death (PCD) pathway. PCD can be classified into three types: apoptosis, necrosis, and autophagy. Results showed that caspase 3 was activated in CHMP5-deficient U937 cells, indicating that the apoptotic pathway was activated, although neither the intrinsic nor the extrinsic apoptotic pathways were activated. Our results also showed that the Granzyme B/Perforin apoptotic pathway was activated by CHMP5 silencing. Necrosis is activated by caspase-independent executioners. In this study, we showed that the apoptosis-inducing protein-mediated necrotic PCD pathway is activated after CHMP5 inhibition. It was found that autophagic PCD did not occur in CHMP5-deficient U937 cells. In conclusion, after CHMP5 inhibition, both Granzyme B/Perforin apoptotic pathway and apoptosis-inducing factor-mediated necrotic pathway were activated, while autophagic pathway was not activated.

Summary: This multicenter retrospective study found that nearly half of COVID-19 patients with ARDS experienced AKI during their hospital stay, and the coexistence of AKI significantly increased the mortality of these patients.

Association of body mass index with severity and mortality of COVID-19 pneumonia: a two-center, retrospective cohort study from Wuhan, China

Summary: This study found that obesity is associated with an increased risk of IMV therapy, ICU admission, and ARDS in COVID-19 pneumonia, while underweight is linked to higher mortality. Additionally, BMI has a U-shaped association with ICU admission and death, and a linear relationship with IMV therapy and ARDS. These findings suggest that caution should be taken in treating COVID-19 patients with underweight and obesity.

Summary: ECMO may be an effective treatment for critically ill patients with COVID-19, but careful patient selection and management by a trained team are crucial. More randomized controlled trials with larger sample sizes are needed to evaluate the actual effectiveness of ECMO in patients with COVID-19.

Diagnostic Value of Bronchoalveolar Lavage Fluid Metagenomic Next-Generation Sequencing in Pneumocystis jirovecii Pneumonia in Non-HIV Immunosuppressed Patients

Summary: This study evaluates the value of metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid (BALF) in the diagnosis of Pneumocystis jirovecii pneumonia (PJP) and its mixed infection in non-human immunodeficiency virus (HIV) immunosuppressed patients. The study found that BALF-mNGS had a higher positive detection rate for various pathogens, especially mixed infections, compared to conventional methods. BALF-mNGS had higher sensitivity and specificity for the diagnosis of PJP compared to traditional methods, and its detection time was significantly shorter.

Summary: This study found a significant increase in EOMES+CD8+ T cells in TKI-resistant lung cancer patients, which was correlated with poor survival. The increase in EOMES+CD8+ T cells was confirmed in both tissue samples and peripheral blood of TKI-resistant patients. The integrated analysis suggested that the increase in EOMES+CD8+ T cells may be related to TRM T cell conversion and metabolic reprogramming.

Lactate induces tumor-associated macrophage polarization independent of mitochondrial pyruvate carrier-mediated metabolism

Xia Fang, Pei Zhao, Shaoyong Gao, Dongmei Liu, Song Zhang, Mengtian Shan, Yuanyuan Wang, Joerg Herrmann, Qiang Li, Feilong Wang

Summary: Tumor cell-derived lactate has been identified as the main factor in the polarization of tumor-associated macrophages (TAMs). Previous studies have highlighted the importance of mitochondrial pyruvate carrier (MPC)-mediated transport in TAMs polarization. However, our genetic depletion study demonstrated that MPC is not necessary for lactate-induced macrophages polarization or tumor growth.It also had no impact on the stabilization of hypoxia-inducible factor 1 alpha (HIF-1 alpha) and histone lactylation, which are both crucial for TAMs polarization. This suggests that lactate itself, rather than its downstream metabolites, is responsible for TAMs polarization.

Updated perspective of EPAS1 and the role in pulmonary hypertension

Na Wang, Jing Hua, Yuhua Fu, Jun An, Xiangyu Chen, Chuancui Wang, Yanghong Zheng, Feilong Wang, Yingqun Ji, Qiang Li

Summary: Pulmonary hypertension (PH) is characterized by irreversible vascular remodeling and elevated pulmonary vascular resistance and pressure, leading to right heart failure and death. Current strategies focus on symptom alleviation through pulmonary vessel dilation. The relationship between PH and hypoxia-inducible factors family, particularly EPAS1, has been studied, but the detailed mechanism is not fully understood. This article provides a comprehensive summary of EPAS1, including its structure, function, and regulatory network in PH and related cardiovascular diseases, and offers theoretical reference for potential novel targets for PH intervention.

Summary: Glycolysis is essential for macrophage activation, but the involvement of glycolytic pathway metabolites in this process is not fully understood. Previous studies suggested the importance of the mitochondrial pyruvate carrier (MPC) in M1 activation, but using genetic approaches, this study shows that MPC is dispensable for M1 macrophage activation. The MPC inhibitor UK5099 inhibits inflammatory responses in M1 macrophages independent of MPC expression.

Identifying critically ill patients at risk of death from coronavirus disease

Summary: This study included 121 critically ill patients, with 28.9% (35/121) of them dying in the hospital. Non-survivors were older and more likely to develop acute organ dysfunction, with higher SOFA and qSOFA scores. Twelve useful biomarkers for predicting in-hospital mortality were identified, such as NLR, FT3, and ferritin, suggesting their potential as powerful predictors for fatal outcomes in COVID-19 patients.
