  • We are studying the role that normal chromatin structure plays in gene regulation in hematopoietic cells and how its disruption leads to altered development and cancer. (stanford.edu)
  • However, in cancer, myeloid cells are largely converted to serve a new master-tumor cells. (aacrjournals.org)
  • Ample evidence supports a key role for MDSCs in immune suppression in cancer, as well as their prominent role in tumor angiogenesis, drug resistance, and promotion of tumor metastases. (aacrjournals.org)
  • During the 1980s and early 1990s, work from the laboratories of Diana Lopez, Jim Talmadge, M. Rita Young, and Hans Schreiber demonstrated that various types of myeloid cells could inhibit immune function in cancer. (aacrjournals.org)

  • Patients with estrogen receptor α positive (ERα+) breast cancer can respond to endocrine therapy, but treatment resistance is common and associated with downregulation of ERα expression in the dormant residual cells. (bvsalud.org)
  • The first dataset was a gene-expression profile that characterizes the cancer cells of a group of acute myeloid leukemia patients. (biomedcentral.com)
  • For this group of patients the biological background of the cancer cells is largely unknown. (biomedcentral.com)
  • Metastatic cancer cells are released from the primary tumor or from other metastases, at an undefined moment of its development, to arrive in the circulation and home at distant sites, where the ecosystem permits them to survive and either remain dormant as micro-metastases or grow to form macro-metastases (Mareel et al. (biomedcentral.com)
  • There is good evidence that cancer cells disseminate from the primary site early during tumor development (Hosseini et al. (biomedcentral.com)
  • TIME influences the immune escape of cancer, the response to immunotherapy, and the survival rate of patients. (biomedcentral.com)
  • OBJECTIVE: The etiology and pathogenesis of Langerhans cell histiocytosis (LCH) remain poorly understood. (thedoctorsdoctor.com)
  • The precise pathogenesis of immune-related diseases remains unclear, and new effective therapeutic choices are required for the induction of remission or cure in these diseases. (biomedcentral.com)
  • Since the vast majority of the morbidity and mortality occurs in immune-naïve African children less than five years of age, with SMA as the primary manifestation of severe disease, this review will focus primarily on the innate immune mechanisms that govern malaria pathogenesis in this group of individuals.

  • BLIMP-1 acts as a master gene regulating the transcriptional network that regulates B cell terminal differentiation. (wikipedia.org)
  • BLIMP-1 regulates T cell activation through a negative feedback loop: T cell activation leads to IL-2 production, IL-2 leads to PRDM1 transcription, and BLIMP-1 feeds back to repress IL-2 gene transcription. (wikipedia.org)
  • Through integrated analysis of single cell chromatin landscapes and gene expression states, coupled with spatial transcriptomic profiling, we are able to impute fibroblast epigenomes with temporospatial resolution. (stanford.edu)
  • Each of these infectious diseases is designated by the major target cell: human monocytic ehrlichiosis is caused by Ehrlichia chaffeensis, and human granulocytic ehrlichiosis by an E. equi -like organism. (cdc.gov)
  • In this way, investigating human immune-related diseases using iPS cells offers distinct advantages over conventional research methods. (biomedcentral.com)
  • This system with the two main parts and their groups makes it possible to combine two (or more) distinct searches into one search result, while being flexible in removing results from the final list. (diva-portal.org)

  • While epidemiological studies show a temporal correlation between enteroviral infections and appearance of anti-islet auto-antibodies (aAbs) [5], investigations using the NOD mouse model suggest that enteroviral infections may accelerate rather than initiate T1D progression, as they are effective only once autoimmune T cells have already accumulated in the islets [6].
