Summary
Cellular immune function, including T cell and NK cell levels, is altered in multiple myeloma (MM) patients. These immune changes correlate with disease severity and prognosis, offering potential therapeutic targets.
Area of Science:
- Immunology
- Hematology
- Oncology
Background:
- Multiple myeloma (MM) is a hematologic malignancy characterized by uncontrolled proliferation of plasma cells.
- Cellular immune dysfunction is increasingly recognized as a critical factor in MM pathogenesis and progression.
- Understanding immune cell dynamics in MM is crucial for developing effective therapeutic strategies.
Purpose of the Study:
- To investigate the status of cellular immune function in patients with multiple myeloma (MM).
- To explore the clinical significance of these immune alterations in relation to disease stage and prognosis.
Main Methods:
- Flow cytometry was used to analyze T cell subtypes, natural killer (NK) cells, dendritic cells (DC), helper T cells (Th1, Th2), regulatory T cells (Treg), and Th17 cells in 45 MM patients.
- Patients were categorized into newly diagnosed, stable stage, and relapsed/refractory groups.
- Serum levels of β2 microglobulin (β2-MG), lactate dehydrogenase (LDH), and hemoglobin (Hb) were measured.
Main Results:
- Newly diagnosed and relapsed/refractory MM patients exhibited significantly lower ratios of CD4+/CD8+, DC1/DC2, and Th1/Th2, along with reduced Treg and NK cell counts compared to controls and stable patients.
- The IL-17A/Treg ratio was significantly higher in newly diagnosed and relapsed/refractory groups, and in patients with higher International Staging System (ISS) stages.
- Negative correlations were observed between CD4+/CD8+, DC1/DC2, Th1/Th2 ratios and β2-MG/LDH levels, while the IL-17A/Treg ratio positively correlated with these markers.
Conclusions:
- Abnormalities in CD4+/CD8+, DC1/DC2, Th1/Th2 ratios, and the IL-17A/Treg balance are closely associated with disease progression and severity in MM.
- These immune dysregulations are linked to treatment outcomes, disease progression, and overall prognosis in MM patients.
- The findings highlight the potential of immune profiling for predicting MM patient outcomes and guiding therapeutic interventions.

4.3K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

8.5K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

01:24T Cell Types and Functions
3.5K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
