Summary: Dengue virus, a prevalent arthropod-borne virus, targets the human protein RIPK1 to evade the innate immune response. This interaction inhibits the activation of NF-kappa B, a key player in inflammation and cell death. The NS3 protein of DENV is responsible for this suppression, independent of its protease activity.

Summary: A new drug candidate called ZJU-37 has been discovered to enhance remyelination by inhibiting the activity of RIPK1 kinase. ZJU-37 not only protects myelin and axons from damage, but also promotes the proliferation of oligodendrocyte progenitor cells to speed up remyelination.

Summary: In this study, it was found that the IKK complex can repress cell death pathways by phosphorylating RIPK1, and the expression of IKK1 and IKK2 is essential for the survival of mature T cells. Additionally, the activation of NF-κB pathway also plays a crucial role in the long-term survival of mature T cells.

Summary: Endogenous neural stem cells (eNSCs) undergo necroptosis during spinal cord injury repair. In vitro experiments show that the necroptosis induced by TSZ treatment regulates the phenotype of NSCs. Necroptosis inhibitors improve NSC survival and phenotype maintenance in vitro and contribute to neuroprotection and repair in vivo. Blocking necroptosis of eNSCs may be a potential therapeutic strategy for treating spinal cord injury.

Summary: RIPK1 is found to promote mTORC1 inhibition during energetic stress, mediating the crosstalk between pro-survival and pro-death pathways. Loss of RIPK1 results in high basal mTORC1 activity, defective lysosomes, and susceptibility to low energy levels. Inhibiting mTORC1 rescues lysosomal defects and vulnerability to energetic stress, prolonging survival in RIPK1-deficient neonatal mice.

Summary: The E3 ubiquitin ligase (E3)-mediated ubiquitination and deubiquitinase (DUB)-mediated deubiquitination play crucial roles in colonic inflammation. Ovarian tumor deubiquitinase 1 (OTUD1) inhibits RIPK1-mediated NF-kappa B activation to alleviate inflammation, with lower expression in UC patients. OTUD1 is a potential target for treating IBD due to its regulatory role in intestinal inflammation.

Summary: This study investigated the role of RIPK1 activation in immune-mediated diabetes or diet induced obesity (DIO). The results showed that Ripk1S25D/S25D mice had normal glucose metabolism and β-cell function. Furthermore, there were no significant differences in immune-mediated diabetes and DIO between Ripk1S25D/S25D and Ripk1+/+ mice.

Summary: Our study reveals a biphasic model of the role of RIPK1 in mediating proinflammatory cytokine production, with distinct temporal roles when caspases are inhibited. Early phase production is NF-κB pathway-mediated and scaffold-dependent, while late phase involves the formation of a novel complex with key signaling mediators. RIPK1 kinase inhibitor Nec-1s can block late phase cytokine production, demonstrating a mechanism for the regulation of inflammatory signaling.

Summary: This study found that C-316-1 has the best suppressive effect on preventing necroptosis and inflammation in AKI. It binds to heat shock protein 90 (Hsp90) and decreases the RIPK1 protein level, thereby limiting necroptosis. These findings suggest that C-316-1 is a potential therapeutic agent against RIPK1-Mediated Necroptosis in AKI.

Summary: RIPK1 acts as a crucial regulator in TNFR1 signaling, controlling cell death, survival, and inflammation. The activation of RIPK1 kinase not only promotes necroptosis and apoptosis, but also induces the transcription of inflammatory cytokines, leading to inflammation. Moreover, activated RIPK1 translocates to the nucleus to interact with the BAF complex, facilitating chromatin remodeling and transcription. This review highlights the proinflammatory role of RIPK1 kinase in human neurodegenerative diseases and discusses the potential of targeting RIPK1 kinase for the treatment of inflammatory pathology in human diseases.

Summary: In this study, the TRIF-dependent complex plays a crucial role in cell death and inflammation response, particularly in the context of bacterial infection. The constitutive binding between ZBP1 and RIPK1 is essential for TRIFosome interactions, caspase-8-mediated cell death, and inflammasome activation. This research provides an alternative model of pro-death complex formation reliant on TRIF signaling, demonstrating a non-canonical cell death pathway controlled by a complex of FADD, RIPK1, caspase-8, and ZBP1.

Summary: This study investigated the repurposing of primidone as a RIPK1 inhibitor in ALS patients. The results showed that primidone can inhibit RIPK1 and significantly reduce serum levels of RIPK1 and IL-8 in ALS patients. The serum levels of RIPK1 and IL-8 may serve as clinical biomarkers for RIPK1 activation in ALS patients.

Summary: Chronic epilepsy models require neurosurgical procedures including depth electrode implants. The intrahippocampal kainate model is a frequently used chronic paradigm, which is based on chemoconvulsant administration and status epilepticus induction during the surgical procedure. This experimental approach raises the question of the extent to which this approach affects postsurgical recovery.

Summary: Bleeding ulcers and erosions are common in active ulcerative colitis, with fibrin layers correlated with rectal bleeding. Neutrophils induce secondary immunothrombosis through PAD4-dependent mechanisms, protecting against acute colitis and rectal bleeding. Deficiency in immunothrombosis can lead to exacerbated colitis and increased bleeding.

Summary: Health monitoring of laboratory rodents is crucial for the validity of animal experiments. Infections of laboratory animals with murine parvoviruses can affect biomedical research data. Traditional diagnostic methods for parvovirus detection often have low sensitivity. We developed a powerful qPCR assay that can quickly and reliably detect murine parvoviruses in various sample materials.

Summary: Multiphoton imaging combined with femtosecond laser-based cellular nanosurgery was used to ablate single cells in colonoids and study the cellular reaction and structure recovery. Targeted crypt damage led to a stop in crypt proliferation and increased Wnt signaling activity. This study provides a new model to better understand organoid dynamics at the single cell level.

Summary: The size of the cecum in germ-free mice is influenced by their genetic background. Mice on B6 background have the largest cecum, while those on C3H background have the smallest cecum. The cecal size of NMRI and BALBc mice is intermediate. The genetic background affects cecal enlargement through regulation of water transport, production of acidic mucins, and metabolic profiles.

Summary: This study reveals that T cell-specific deficiency of RIPK1 in mice leads to premature T cell senescence and age-related diseases, resulting in premature death. RIPK1 deficiency activates mTORC1, leading to enhanced cytokine production, induction of senescence-related genes, and increased caspase-3/7 activation. The impaired phenotypes and responses are restored by combined deficiency of RIPK3 and caspase-8 inhibition.

Summary: Rodent behavior is influenced by environmental conditions, including housing conditions and familiarization with the experimenter. This study aimed to investigate the effects of different housing conditions and experimenter familiarization on pain-related behavior in male mice with peripheral neuropathy. The results showed that housing conditions and experimenter familiarization had an impact on mechanical sensitivity, gait pattern, anxiety-like behavior, and stress levels in the mice. These findings highlight the importance of considering environmental conditions in preclinical pain studies.

Summary: This study evaluated the feasibility of using gene-edited CAR-T cell therapies for treating Burkitt lymphoma. The results showed that both edited CAR-T cells exhibited cytotoxic effects against Burkitt lymphoma cells in vitro, and CD19(KI)CAR-T cells delayed lymphoma dissemination in vivo while gp350(KI)CAR-T cells reduced EBV DNA load. However, the two types of CAR-T cells showed differences in therapeutic effects and in vivo dynamics, reflecting the complexity of EBV immune escape mechanisms.
