how to differentiate reactive lymphocyte from monocyte

The main difference between monocytes and lymphocytes is that the monocytes are responsible for the destruction of pathogens by phagocytosis whereas the lymphocytes are responsible for triggering a specific immune response. No granules or azurophilic (reddish) granules . The cytoplasm in reactive lymphocytes is often a deep blue, with darker edges at the contact point with other cells. The groups were compared for demographics, duration of symptoms, monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), white blood cell count, neutrophil percentage (NP), C-reactive protein (CRP), mean .

New biomarkers are urgently required to assess disease severity. They are usually larger than a lymphocyte and at least the size of a monocyte. immune response. Monocytes are highly plastic and heterogeneous, and change their functional phenotype in response to environmental stimulation. Content uploaded by Hilary Denis . This indicated that the difference in the monocyte-to-lymphocyte ratio between the lymphoma and non-lymphoma groups remained significant after considering the other confounders. Reactive lymphocytes - particularly big ones - can look a lot like monocytes. Function. A monocyte count of 483 and L/M ratio of 3.1 were 60% sensitive and had a specificity of 61% and 53%, respectively for active UC. During inflammation, pro-inflammatory cytokines and chemokines, can generate monocytes in the bone marrow and recruit them to the site of inflammation.

Human LFA-1 is a widely expressed leukocyte antigen present in lymphocytes, thymocytes, monocytes, granulocytes, and 37 % of bone marrow cells (3). The major difference between Monocytes and Lymphocytes is that Monocytes are large phagocytic white blood cells with a simple oval nucleus and lymphocytes are small white blood cells with a single round nucleus. Background Recently, reports have classified lymphocyte to monocyte ratio (LMR) as an effective indicator for predicting the prognosis of pancreatic cancer. The neutrophil-lymphocyte ratio (NLR), in addition to the platelet-lymphocyte ratio (PLR) and lymphocyte-monocyte ratio (LMR), is a simple biomarker of systemic inflammation and has been reported to be a highly sensitive measure of inflammation in the field of oncology (i.e., gastric cancer, [9] breast cancer, [10] prostate cancer [11] and non . Lymphocytes, subtypes of leucocytes, play an important role in the postischaemic inflammation.12 Monocytes also have a pivotal role in the systemic inflammatory response, having been traditionally considered to differentiate into three major subtypes in humans and to exert diverse effects in postischaemic pathobiology.13 Lately, the lymphocyte . A monoclonal antibody (TA-1) reactive with human T lymphocytes and She has a history significant for rheumatoid arthritis and anemia of chronic disease. Results: The difference between the two groups in terms of age, gender, side of the disease, and monocyte count was not statistically significant (p > 0.05) whereas WBC count, lymphocyte, and LMR was significantly higher in the TE group (p < 0.05).
