    Applications
    CD33 is a protein that has been studied in various applications. In the context of neuroinflammation and Alzheimer's disease (AD), CD33 has been identified as a potential risk factor for neuroinflammation. It is involved in the upregulation of proinflammatory factors and contributes to the accumulation of toxic tau and amyloid-beta in the brain. CD33 is also associated with the homeostasis of synaptic transmission and its remodeling by pruning. In the field of hematopoietic stem/progenitor cell (HSPC) transplantation, CD33 has been targeted for deletion or modification to protect normal HSPCs from unwanted toxicities. Studies have shown efficient long-term engraftment of CD33-edited HSPCs in nonhuman primates without adverse effects on their functionality. Additionally, CD33 has been investigated in the diagnosis of chronic myeloid leukemia (CML) using flow cytometry. It has been found that CD33 expression is increased in CML patients, along with other markers, providing insights for the diagnosis of the disease. Furthermore, CD33 has been implicated in the interplay of hematological parameters, CD markers, genetic polymorphisms, and database mutations in acute myeloid leukemia (AML) patients. The expression of CD33 and other markers was found to be upregulated in AML patients, and mutations in the IL15 gene, which is associated with AML, were identified. Overall, CD33 has diverse applications in the fields of neuroinflammation, HSPC transplantation, and the diagnosis and understanding of leukemia.

    Published Data

    Fig.1 Suppression of the native mouse Human CD33m is inhibited by CD33, which increases phagocytosis in BV-2 cells.

    When human CD33m is knocked down, it stops human CD33m from increasing phagocytosis. BV-2 cells expressing human CD33 variants were treated with either mouse CD33 targeting RNAi or control/scrambled RNAi, and flow cytometry was used to measure the percentage of rat neuronal debris that was phagocytosed. N is the number of separate cell culture preparations. Solid lines connect repeats performed with the four variant cell lines on the same day.

    Research Highlights

    E Petty, Nicholas. et al. "Efficient long-term multilineage engraftment of CD33-edited hematopoietic stem/progenitor cells in nonhuman primates." Molecular therapy. Methods & clinical development, 2023.
    The current study focuses on identifying immunotherapeutic targets that are shared between neoplastic and normal hematopoietic stem and progenitor cells (HSPCs). This is an important issue as it can lead to unwanted toxicities in non-target cells. The researchers aimed to delete or modify these shared targets in order to protect the normal HSPCs. They used a gene-editing technique to delete the V-set domain of CD33, a commonly targeted immune-dominant domain, in the HSPCs of two rhesus macaques. After successful engraftment and up to 20% long-term gene editing in the HSPCs and blood cell lineages, the researchers concluded that this modification did not affect the functionality or differentiation potential of myeloid cells.

    Huang, Wei. et al. "Role of Flow Cytometry in the Diagnosis of Chronic Myeloid Leukemia." Zhongguo shi yan xue ye xue za zhi, 2023.
    The aim of this study was to examine the immunological phenotype of chronic myeloid leukemia (CML) and to investigate its characteristics and significance. CML is a type of cancer that affects the white blood cells. The researchers analyzed data from patients with CML to better understand the condition. Through their analysis, they were able to identify key characteristics of the immunological phenotype in CML and determine its significance in the disease. This study provides valuable insights into the immunological aspects of CML for further research and treatment strategies.
