Insights
Chronic lymphocytic leukemia (CLL) cells express CD5 antigen, unlike normal B lymphocytes. Advanced CLL stages may show a decrease in normal B cells, though disease progression showed no clear correlation with studied parameters.
Area of Science:
- Immunology
- Hematology
- Oncology
Background:
- Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of malignant B lymphocytes.
- CLL cells uniquely express the CD5 antigen, typically associated with T cells, distinguishing them from normal B cells.
Purpose of the Study:
- To investigate the expression of CD5 and DR antigens on both normal and malignant B cells in CLL patients.
- To evaluate potential correlations between B cell compartment characteristics and disease progression.
Main Methods:
- Utilized two-colour immunofluorescence techniques.
- Employed CD5-TRITC and DR-FITC staining to analyze B cell populations.
Main Results:
- No significant correlation was observed between disease progression and the studied immunological parameters.
- A trend towards a reduction in normal B lymphocytes was noted in patients with advanced stages of CLL.
Conclusions:
- The CD5 marker's presence on CLL cells remains a key diagnostic feature.
- While not directly correlated with progression, a decline in normal B cells in advanced disease warrants further investigation.
Abstract:
In contrast to normal B lymphocytes, CLL cells express CD5 antigen believed to be a T cell marker. We have assessed normal and malignant B cell compartments in CLL patients with the aid of two-colour immunofluorescence techniques (CD5-TRITC, DR-FITC). No clear correlation was found between progression of disease and parameters studied. However, there was a tendency for a diminution of normal B cells in advanced stages of disease.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
