Can autoimmune disease cause low monocytes?
You may also see monocytes noted as a percentage of your white blood cell count, rather than as an absolute number. Low levels can result from certain medical treatments or bone marrow problems while high levels can indicate the presence of chronic infections or an autoimmune disease.
How high is too high for monocytes?
Monocytosis or a monocyte count higher than 800/µL in adults indicates that the body is fighting an infection. Monocytosis or a monocyte count higher than 800/µL in adults indicates that the body is fighting an infection.
Does lupus cause high monocytes?
The effect of monocyte stimulation on acid phosphatase activity is the same in lupus and normal monocytes. Taken together, these observations suggest that the increased numbers of monocytes in lupus patients and some subtle functional differences in these cells may be important in the progression of this disease.
What autoimmune disease has low white blood cells?
A low white blood cell count can be an indicator of certain conditions, including lupus, rheumatoid arthritis, vitamin deficiencies, or a side effect of cancer treatment.
What labs would indicate lupus?
Blood and urine tests may include:
- Complete blood count. This test measures the number of red blood cells, white blood cells and platelets as well as the amount of hemoglobin, a protein in red blood cells.
- Erythrocyte sedimentation rate.
- Kidney and liver assessment.
- Urinalysis.
- Antinuclear antibody (ANA) test.
Is the human macrophage cell line U937 an in vitromodel?
The human macrophage cell line U937 as an in vitromodel for selective evaluation of mycobacterial antigen-specific cytotoxic T-cell function J S Passmore,*P T Lukey,†and S R Ress*
Does RhoA/ROCK signaling induce macrophage differentiation from U937 cells?
In order to investigate the effects of RhoA/ROCK signaling in macrophage differentiation, we used 100 ng/mL PMA to induce macrophage differentiation from U937 cells in vitro. The observation of cell morphology and the expression of CD68 and SR-A were performed to confirm the differentiation induced by PMA.
Are mycobacterial antigens adaptable to human MΦ cell line U937?
This study describes a relatively simple, robust and easily adaptable in vitromodel that makes use of the human Mφ cell line, U937,17to present mycobacterial antigens to human HLA class I-restricted CD8+CTL.
How do you induce U937 cells to differentiate?
U937 cells were induced to differentiate by exposing the cells (5 × 105cells/ml) to 5 ng/ml of phorbol 12-myristate 13-acetate (PMA) (Sigma, St. Louis, MO), 200 IU/ml of recombinant interferon-γ (IFN-γ) (Biomedical PBL Laboratories, New Brunswick, NJ) or 10−7m1,25-dihydroxyvitamin D3(VD3) (Roche Pharmaceuticals, Nutley, NJ), for 48 hr.
