| 설명 | 면역기능을 담당하는 세포. 골수에서 만들어지며, 림프구는 크게 2가지로 대분된다. 이른바 T림프세포, B림프세포로 나뉘어지게 된다. T림프세포는 세포성면역에 관여하며, 주로 바이러스병에 대한 면역기능이나, 알레르기(면역반응 4번형 등) 등에 관여한다. 이에 비해 B림프세포는 체액성면역에 관여하여, 항원 항체 반응을 일으키는 항체를 생산하고 주로 세균감염에 대한 면역기능을 담당한다. |

| 설명 | 림프계세포(림프구)는 크게 2가지로 대분된다. 이른바 T림프세포(T-cell), B림프세포(B-cell)로 나뉘어진다. T림프세포는 세포성 면역에 관여하며, 주로 바이러스병에 대한 면역기능이나, 알레르기 등에 관여한다. 이에 비해 B림프세포는 체액성 면역에 관여하여, 항원 항체 반응을 일으키는 항체를 생산하고 주로 세균성 질환에 대한 면역 기능을 담당한다. T-림프구는 면역기능에 가장 중요한 역할을 하는 세포로서 세포면역을 담당하며 B-cell의 작용을 조절하는 기능도 있다. 골수에서 생성되어 가슴샘에서 성숙된다. 크게 보조T세포(helper T-cell: 면역작용의 발생을 보조한다)와 T세포(suppressor T-cell: 면역작용의 발생을 억제한다)로 구분되며 이들은 세포 표면에 분포하는 항원에 의해서 식별될 수 있다. |

| t4 helper lymphocyte | A specific type of lymphocyte, derived from the thymus gland, that plays an important role in cellular immunity. T4 lymphocytes (CD4 cells) are decreased (absolute counts less than 200) in patients with AIDS resulting in compromised immune function. (27 Sep 1997) |
|---|
| helper t lymphocyte | <haematology, immunology> A type of white blood cell produced by the thymus gland whose presence is necessary for normal levels of antibodies to be produced by B lymphocytes, both in the body (in vivo) and in experimental situations (in vitro). (09 Oct 1997) |
|---|---|
| lymphocyte lymphocyte | A type of non-granular antibodies. (09 Oct 1997) |
| helper cell | A subset of T lymphocytes that acts in cooperation with B lymphocytes to permit antibody formation. Synonym: inducer cell. (05 Mar 2000) |
| helper factor | A group of factors apparently produced by helper T lymphocytes that act specifically or non-specifically to transfer T-cell help to other classes of lymphocytes. The existence of specific T-cell helper factor is uncertain. (18 Nov 1997) |
| helper phage | A virus which helps a separate and unrelated defective virus reproduce by infecting the same host cell that is already occupied by the defective virus and providing the proteins which the defective virus is missing and needs to complete its life cycle. (09 Oct 1997) |
| helper virus | <virology> A virus that will allow the replication of a co-infecting defective virus by producing the necessary protein. (18 Nov 1997) |
| helper viruses | Viruses which enable defective viruses to replicate or to form a protein coat by complementing the missing gene function of the defective (satellite) virus. Helper and satellite may be of the same or different genus. (12 Dec 1998) |
| T helper cell | <haematology, immunology> Sets of T lymphocytes that specifically are involved in the differentiation of B lymphocytes into antibody secreting cells. Loss of T helper cells, as in HIV infection, leads to immunosuppression. There is also T-cell help of T-cell function. TH1 and TH2 are now recognised, TH1 helping with cellular, TH2 with humoural immunity. (16 Dec 1997) |
| t-helper cell | Immune cells that are triggered by antibodies to seek and attack invading organisms. Cells called macrophanges summon t-helper cells to the site of the infection and present a protruding antigen onto which the t-helper cell locks, thus recognizing the invading substance. The t4-helper cell then reproduces and secretes its potent lymphokine hormones that stimulate B-cell production of antibodies; signal natural killer or cytotoxic (cell-killing) T-cells; and summon more macrophanges to the site of the infection. T-helper cells are also called t4 cells and are normally twice as common as t8 cells. If a person has aids, the proportion of t4 to t8 cells is often reversed. (12 Dec 1998) |
| T helper cells | A subset of lymphocytes that secrete various cytokines that regulate the immune response. (05 Mar 2000) |
| T-lymphocytes, helper-inducer | Subpopulation of CD4+ lymphocytes that cooperate with other lymphocytes (either t or b) to initiate a variety of immune functions. For example, helper-inducer T-cells cooperate with B-cells to produce antibodies to thymus-dependent antigens and with other subpopulations of T-cells to initiate a variety of cell-mediated immune functions. (12 Dec 1998) |
| Friend helper virus | <virology> Mouse (lymphoid) leukaemia virus present in stocks of Friend virus, that was believed at one time to assist its replication. Molecular cloning of Friend virus has since shown that it is nondefective. (18 Nov 1997) |
| antigens, differentiation, b-lymphocyte | Membrane antigens associated with maturation stages of B-lymphocytes, often expressed in tumours of B-cell origin. (12 Dec 1998) |
| antigens, differentiation, t-lymphocyte | Antigens expressed on the cell membrane of T-lymphocytes during differentiation, activation, and normal and neoplastic transformation. Their phenotypic characterization is important in differential diagnosis and studies of thymic ontogeny and T-cell function. (12 Dec 1998) |
| bare lymphocyte syndrome | <syndrome> Absence of HLA antigens on peripheral mononuclear cells, which may result in immunodeficiency. (05 Mar 2000) |
