Lymphocryptovirus
|
D018143 |
[A genus of the family HERPESVIRIDAE, subfamily GAMMAHERPESVIRINAE, infecting B-cells in humans and new world primates. The type species human herpesvirus 4 (HERPESVIRUS 4, HUMAN) is better known as the Epstein-Barr virus.

|
Lymphocyte Activation
|
D008213 |
[Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

Lymphocyte Antigen 96
|
D051218 |
[A secreted protein that associates with TOLL-LIKE RECEPTOR 4 and is essential for receptor recognition of LIPOPOLYSACCHARIDES.

Lymphocyte Cooperation

D008211 |
[T-cell enhancement of the B-cell response to thymic-dependent antigens.

Lymphocyte Count
|
D018655 |
[The number of LYMPHOCYTES per unit volume of BLOOD.

|
Lymphocyte Culture Test, Mixed
|
D007959 |
[Measure of histocompatibility at the HL-A locus. Peripheral blood lymphocytes from two individuals are mixed together in tissue culture for several days. Lymphocytes from incompatible individuals will stimulate each other to proliferate significantly (measured by tritiated thymidine uptake) whereas those from compatible individuals will not. In the one-way MLC test, the lymphocytes from one of the individuals are inactivated (usually by treatment with MITOMYCIN or radiation) thereby allowing only the untreated remaining population of cells to proliferate in response to foreign histocompatibility antigens.

|
Lymphocyte Depletion
|
D008212 |
[Immunosuppression by reduction of circulating lymphocytes or by T-cell depletion of bone marrow. The former may be accomplished in vivo by thoracic duct drainage or administration of antilymphocyte serum. The latter is performed ex vivo on bone marrow before its transplantation.

|
Lymphocyte Function-Associated Antigen-1
|
D016169 |
[An integrin heterodimer widely expressed on cells of hematopoietic origin. CD11A ANTIGEN comprises the alpha chain and the CD18 antigen (CD18 ANTIGENS) the beta chain. Lymphocyte function-associated antigen-1 is a major receptor of T-CELLS; B-CELLS; and GRANULOCYTES. It mediates the leukocyte adhesion reactions underlying cytolytic conjugate formation, helper T-cell interactions, and antibody-dependent killing by NATURAL KILLER CELLS and granulocytes. Intracellular adhesion molecule-1 has been defined as a ligand for lymphocyte function-associated antigen-1.

Lymphocyte Specific Protein Tyrosine Kinase p56(lck)
|
D019860 |
[This enzyme is a lymphoid-specific src family tyrosine kinase that is critical for T-cell development and activation. Lck is associated with the cytoplasmic domains of CD4, CD8 and the beta-chain of the IL-2 receptor, and is thought to be involved in the earliest steps of TCR-mediated T-cell activation.

Lymphocyte Subsets
|
D016131 |
[A classification of lymphocytes based on structurally or functionally different populations of cells.

Lymphocyte Transfusion
|
D017710 |
[The transfer of lymphocytes from a donor to a recipient or reinfusion to the donor.
] |
|
Lymphocytes
|
D008214 |
[White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.

|
Lymphocytes, Null
|
D008215 |
[A class of lymphocytes characterized by the lack of surface markers specific for either T or B lymphocytes.
] |
|
Lymphocytes, Tumor-Infiltrating
|
D016246 |
[Lymphocytes that show specificity for autologous tumor cells. Ex vivo isolation and culturing of TIL with interleukin-2, followed by reinfusion into the patient, is one form of adoptive immunotherapy of cancer.
] |
|
Lymphocytic Choriomeningitis
|
D008216 |
[A form of meningitis caused by LYMPHOCYTIC CHORIOMENINGITIS VIRUS. MICE and other rodents serve as the natural hosts, and infection in humans usually occurs through inhalation or ingestion of infectious particles. Clinical manifestations include an influenza-like syndrome followed by stiff neck, alterations of mentation, ATAXIA, and incontinence. Maternal infections may result in fetal malformations and injury, including neonatal HYDROCEPHALUS, aqueductal stenosis, CHORIORETINITIS, and MICROCEPHALY. (From Joynt, Clinical Neurology, 1996, Ch26, pp1-3)

Lymphocytic choriomeningitis virus
|
D008217 |
[The type species of ARENAVIRUS, part of the Old World Arenaviruses (ARENAVIRUSES, OLD WORLD), producing a silent infection in house and laboratory mice. In humans, infection with LCMV can be inapparent, or can present with an influenza-like illness, a benign aseptic meningitis, or a severe meningoencephalomyelitis. The virus can also infect monkeys, dogs, field mice, guinea pigs, and hamsters, the latter an epidemiologically important host.
