AI Article Synopsis

  • - The complement system is essential for both innate and adaptive immunity, helping to eliminate pathogens and damaged cells like cancer cells.
  • - It is highly regulated and works closely with cell-mediated immunity, affecting how immune responses are carried out.
  • - In the tumor microenvironment, the complement system has both immune and non-immune roles that can enhance immune evasion and support tumor growth, sometimes regardless of complement activation.

Article Abstract

The complement system plays crucial roles in both innate and adaptive immune responses, facilitating the elimination of pathogens such as microorganisms and damaged cells, including cancer cells. It is tightly regulated and integrated with cell-mediated immunity. In the tumor microenvironment, the complement system performs both immune and nonimmune functions in tumor and immune cells through pathways that depend on or are independent of complement activation, thereby promoting immune evasion and tumor progression.

Role of immune cell homeostasis in research and treatment response in hepatocellular carcinoma.

Introduction Recently, immune cells within the tumor microenvironment (TME) have become crucial in regulating cancer progression and treatment responses. The dynamic interactions between tumors and immune cells are emerging as a promising strategy to activate the host's immune system against various cancers. The development and progression of hepatocellular carcinoma (HCC) involve complex biological processes, with the role of the TME and tumor phenotypes still not fully understood.

Introduction: The transporter associated with antigen processing (TAP) is a key component of the classical HLA I antigen presentation pathway. Our previous studies have demonstrated that the downregulation of TAP1 contributes to tumor progression and is associated with an increased presence of myeloid-derived suppressor cells (MDSCs) in the tumor microenvironment. However, it remains unclear whether the elevation of MDSCs leads to immune cell exhaustion in tumors lacking TAP1.

Melanoma is an immunogenic tumor. The melanoma tumor immune microenvironment (TIME) is made up of a heterogenous mix of both immune and non-immune cells as well as a multitude of signaling molecules. The interactions between tumor cells, immune cells and signaling molecules affect tumor progression and therapeutic responses.

Background: Neuroblastoma is a heterogeneous disease with adrenergic (ADRN)- and therapy resistant mesenchymal (MES)-like cells driven by distinct transcription factor networks. Here, we investigate the expression of immunotherapeutic targets in each neuroblastoma subtype and propose pan-neuroblastoma and cell state specific targetable cell-surface proteins.

Methods: We characterized cell lines, patient-derived xenografts, and patient samples as ADRN-dominant or MES-dominant to define subtype-specific and pan-neuroblastoma gene sets.

The gut microbiome plays a key role in human health, influencing various biological processes and disease outcomes. The historical roots of probiotics are traced back to Nobel Laureate Élie Metchnikoff, who linked the longevity of Bulgarian villagers to their consumption of sour milk fermented by Lactobacilli. His pioneering work led to the global recognition of probiotics as beneficial supplements, now a multibillion-dollar industry.
