From trash to treasure: tumor draining lymph nodes as a multi-omics goldmine in cancer therapy.

Tumor draining lymph nodes (TDLNs), as secondary lymphoid organs, are pivotal in initiating and regulating adaptive immune responses. Historically, TDLNs were recognized primarily as metastasis gateways in cancer, promoting radical dissection to prevent recurrence. However, emerging preclinical studies reveals their critical role in orchestrating systemic anti-tumor immune responses during cancer therapy, highlighting the dilemma of balancing lymph nodes (LNs) preservation with metastasis control.

CLE19 suppresses brassinosteroid signaling output via the BSL-BIN2 module to maintain BES1 activity and pollen exine patterning in Arabidopsis.

The pollen exine serves as a protective barrier and signaling interface essential for male fertility in flowering plants. Its precise patterning depends on coordinated interactions between microspores and tapetal cells. While the CLAVATA3/EMBRYO SURROUNDING REGION-related 19 (CLE19) peptide has been identified as a microspore-derived "brake" that restricts tapetal activity to maintain exine developmental homeostasis, how CLE19 integrates with hormonal signaling pathways remains poorly understood.

Brain-infiltrating ILC2s boost poststroke angiogenic initiation through α-CGRP production.

Group 2 innate lymphoid cells (ILC2s) regulate immunity and tissue repair but are rarely found in the brain. Whether ILC2s can infiltrate the brain from bloodstream and the underlying mechanisms involved remain unclear. While ILC2s have recently been identified as key immunosuppressive players in neuroinflammation, their role in brain tissue repair remains promising but underexplored.

Regulatory T cells as novel cell-based therapy for ischemic stroke.

Ischemic stroke is a leading cause of mortality worldwide, with an excessive immune response playing a major role in exacerbating post-stroke pathogenesis. Regulatory T (Treg) cells, known for their immunosuppressive properties, are believed to be crucial in mitigating post-stroke inflammation. Moreover, emerging evidence suggests that Treg cells contribute to ischemic stroke recovery by suppressing neurotoxic astrogliosis and by promoting myelination regeneration.

Plasmablast-like lymphoma cells as a distinct subpopulation confers multidrug resistance in PCNSL.

Background: Primary central nervous system lymphoma (PCNSL) is a highly aggressive subtype of non-Hodgkin lymphoma that is confined to the central nervous system. PCNSL is associated with a poor 5-year survival rate of 30-40%, partly due to a high recurrence rate of 60%. A comprehensive understanding of the molecular signatures and mechanisms underlying drug resistance in PCNSL is crucial, as it has significant implications for therapeutic strategies.

It is one of the necessary processes to explore key microbial functions and interactions by studying keystone species.

Endothelial Changes at Different Stages After Ischemic Stroke Contribute to the Regulation of Immune Cell Infiltration.

Aims: Following ischemic stroke, peripheral immune cell infiltration is characterized by myeloid cell predominance in the acute phase and lymphoid cell infiltration in the subacute to chronic phases. Endothelial cells, as a critical interface between the peripheral circulation and the brain, upregulate adhesion molecules to facilitate immune cell infiltration. However, it remains unclear whether endothelial cells exhibit functional differences at different stages after ischemic stroke and how these differences affect immune cell infiltration.

Viral diversity and auxiliary metabolic genes in rare earth element mine drainage in South China.

In extreme environments, viruses play a crucial role in regulating the structure and metabolic activities of microbial communities, thereby impacting the overall biogeochemical cycles. Previous research found that rare earth element acid mine drainage (REE-AMD) harbors a wide array of microbial species. However, our understanding of the viruses that infect these microorganisms remains limited.

Repair-associated macrophages increase after early-phase microglia attenuation to promote ischemic stroke recovery.

Ischemic stroke recovery involves dynamic interactions between the central nervous system and infiltrating immune cells. Peripheral immune cells compete with resident microglia for spatial niches in the brain, but how modulating this balance affects recovery remains unclear. Here, we use PLX5622 to create spatial niches for peripheral immune cells, altering the competition between infiltrating immune cells and resident microglia in male mice following transient middle cerebral artery occlusion (tMCAO).

Affinity-based protein profiling of MDM2 inhibitor Navtemadlin.

Navtemadlin is a potent inhibitor of the p53-MDM2 protein-protein interaction, which plays a critical role in the proliferation of p53-wildtype tumours. Whilst Navtemadlin has progressed to multiple Phase III clinical trials in oncology, little has been disclosed regarding its selectivity for MDM2 in cells. Here, we report the synthesis and validation of photoactivatable clickable probes of Navtemadlin, and their application to target discovery for Navtemadlin through affinity-based protein profiling.

New insights into efficient iron sulfide oxidation for arsenic immobilization by microaerophilic and acidophilic Fe(II)-oxidizing bacteria under micro-oxygen and acidic conditions.

Microbial-mediated FeS oxidation to Fe(Ⅲ) minerals via chemolithoautotrophic Fe(Ⅱ) oxidizers under pH/O₂ limitations engages As immobilization. However, this process is constrained under the dual stress of micro-oxygen and acidic conditions due to the critically diminished Fe(Ⅱ) oxidation capacity. Therefore, the interplay between Fe(Ⅱ) oxidation, carbon metabolism, and As immobilization in Fe(Ⅱ)-oxidizing bacteria under micro-oxygen and acidic conditions remains unclear.

Novel subsets of peripheral immune cells associated with promoting stroke recovery in mice.

Aims: Peripheral immune cells infiltrating into the brain trigger neuroinflammation after an ischemic stroke. Partial immune cells reprogram their function for neural repair. Which immune cells promote ischemic brain recovery needs further identification.
