Several recent genome-wide association studies (GWAS) in patients with neurodegenerative disorders have shed new light on the brain immune system, suggesting that it plays a pivotal role in disease pathogenesis. Mononuclear phagocytes are blatantly involved in Alzheimer's disease (AD) of the central nervous system (CNS), but the specific functions of resident microglia, perivascular or meningeal macrophages, and circulating myeloid cells have not yet been fully resolved. Next-generation sequencing, high-throughput immune profiling technologies, and novel genetic tools have recently revolutionized the characterization of innate immune responses during AD. These studies advocate selective and non-redundant roles for myeloid subsets, which could be a target for novel disease-modifying therapies in AD.

Cell-to-cell heterogeneity in lipid signaling underlies variations in response and recurrence for many cancers, including leukemias. A highly parallel, miniaturized thin-layer chromatographic platform capable of assaying single cells was developed. Ultrasmall volumes (50 pL) of standard fluorescent lipids were separated with excellent repeatability, reproducibility, and limits of detection.

Objectives: To study the predictive role of tumor-associated neutrophils in early luminal HER2-negative breast cancer.

Materials And Methods: This is a retrospective study conducted on 60 women cases aged from 31 to 79 years underwent surgery for luminal HER2-negative ductal breast cancer in tertiary care cancer centre. We first estimated basic morphological signs: tumor size, tumor grade (by Nottingham Histologic Score), tumor infiltrating lymphocytes (TILs), Lymphovascular invasion, hormonal receptors status, proliferative index, and regional lymph nodes metastasis.

Novel strategies to disrupt tumor progression have emerged from studying the interactions between tumor cells and tumor-associated macrophages (TAMs). However, the molecular mechanisms of interactions between tumor cells and TAMs underlying oral squamous cell carcinoma (OSCC) progression have not been fully elucidated. This study explored the molecular mechanism of the HSP27/IL-6 axis in OSCC chemoresistance, invasion, and migration.

Inflammatory cytokines are fundamental mediators of the organismal response to injury, infection, or other harmful stimuli. To elucidate the early and mostly direct transcriptional signatures of inflammatory cytokines, we profiled all immunologic cell types by RNAseq after systemic exposure to IL1β, IL6, and TNFα. Our results revealed a significant overlap in the responses, with broad divergence between myeloid and lymphoid cells, but with very few cell-type-specific responses.
