| 영문 | cell | 한글 | 세포 |
|---|---|---|---|
| 설명 | 생명체를 이루는 구조적, 기능적 단위. 핵의 유무에 따라서 유핵세포와 무핵세포로 나눌 수가 있다. 무핵세포란 핵이 없는 세포를 말한다. 핵이란 유전정보를 가지고 있는 염색체를 보관하는 곳인데 무핵세포에서는 염색체가 세포속에 그냥 노출되어 있다. 대개 세포 하나하나가 독립된 생명체의 역할을 하는 단세포생물로서 외부환경으로부터 자신을 보호할 수 있는 견고한 세포벽을 가지고 있다. 유핵세포란 핵을 가지고 있어서 유전정보가 있는 염색체가 세포의 다른 부분과 구분되어 핵속에 들어있다. 세포속에서 핵외의 부분(이를 세포질이라 한다)에는 여러 가지 세포의 소기관이 있어서 세포의 다양한 기능을 분담한다. ◈유핵세포의 기본 구조 1.세포막-세포를 둘러싸서 주위환경과 분리하여 세포의 내환경을 유지한다. 2.형질내세망(endoplasmic reticulum)-단위막으로 둘러쌓여 있는 불규칙한 망상구조이다. 이 망상구조의 내부를 소강, 소조라고 부른다. 여기에는 표면이 매끈한 무과립형질내세망과 표면이 불규칙한 과립형질내세망의 두 가지가 있다. 과립형질내세망의 경우는 표면에 단백질을 합성하는 리보솜이라는 것이 부착되어 있다. 이곳은 주로 세포밖으로 분비할 단백질을 합성하는 장소이다. 무과립형질내세망은 표면에 리보솜이 부착되어 있지 않은 것을 말하며, 이곳에서는 주로 해독작용, 글리코겐의 합성, 스테로이드호르몬의 합성 등이 일어난다. 3.리보솜-단백질을 합성하는 역할을 하는 곳이다.이것은 세포질에 존재하는 자유리보솜과 과립형질내세망에 부착이 되어 존재하는 부착리보솜의 두 가지로 나눈다. 자유리보솜은 주로 세포내에서 필요한 단백질을 만드는 역할을 하고 부착리보솜은 세포밖으로 분비할 단백질을 만드는 역할을 한다. 4.골지장치(Golgi apparatus)-핵주위에 분포하는 납작해진 주머니모양의 것이 중첩되어 형성된 층판 모양의 구조물로 과립형질내세망에서 생성되어 외부로 분비될 단백질을 모아서 농축, 포장하여 과립을 만드는 역할을 한다. 5.사립체(mitochondria)-구형, 난형의 긴 막대기 모양으로 크기가 다양한 구조물. 생물체의 에너지 저장물질인 ATP를 생산하는 역할을 한다. 또 세포와 다른 자신만의 유전정보를 가진 DNA, RNA를 가지고 있다. 모양, 크기가 세균과 비슷하며 자체증식성 등 독립된 생명체로서 필요한 요건을 갖추고 있어서 세포와 공생관계를 가진 독립된 세포로 생각하고 있다. 6.용해소체(lysosome)-작은 구형의 소체로 여러 가지 분해효소를 가진다. 세포외계에서 들어온 물질과 결합하여 그 물질들을 용해하는 역할을 하고, 오래된 세포소기관들을 제거하는 역할도 한다. 7.세포핵(nucleus)-구형, 난형으로 세포의 중심에 위치한다. 핵내에는 유전정보가 있는 물질인 염색체가 존재한다. 8.중심소체(centrosome)-핵주위에 존재하면서 핵의 분열시에 양쪽의 염색체를 당기는 작은 섬유를 만드는 역할을 하는 곳.  |

|---|---|---|---|
| 설명 | 면역이란 신체를 외부의 물질로부터 보호하는 행위를 말한다. 여기에는 특이적 면역과 비특이적 면역의 두 가지가 있다. 비특이적 면역이라함은 특정한 물질에 관계하는 면역이 아니라 특정 대상이 없이 모든 외부 물체에 작용할 수 있는 면역을 말한다. 여기에는 소변의 흐름, 눈물의 흐름, 피부의 비투과성 등의 기계적인 것도 포함되고 피속에 돌아다니는 세포 중에서 비특이적으로 외부의 물질을 포식하는 세포들(예를 들면 큰포식세포(macrophage)의 활동도 포함이 된다. 세포매개면역이란 특이한 물질을 감지할 수 있는 세포를 생성하게 하여 그것으로 하여금 그 물질을 포식하게 하는 것을 말한다. |

| natural killer cell | <haematology, immunology> A certain type of white blood cell that attacks tumour cells and infected body cells by binding to a tumour cell and releasing lethal chemicals. Natural killer cells are thought to play a key role in cancer prevention by killing abnormal cells before they multiply and grow. (16 Dec 1997) |
|---|---|
| natural killer cell stimulating factor | <cytokine> A 75 kD heterodimeric cytokine composed of disulfide-bonded 40 kD and 35 kD subunits that was originally identified by its ability to induce cytotoxic effector cells in synergy with less than optimal concentrations of interleukin-2. It is released by macrophages in response to infection and promotes the activation of cell-mediated immunity. Specifically, IL-12 triggers the maturation of Thl CD4 cells, specific cytotoxic T-lymphocyte responses and an increase in the activity of NK cells and consequently, it is the initiator of cell-mediated immunity. It enhances the lytic activity of NK cells, induces interferon production, stimulates the proliferation of activated T-cells and NK cells. Is secreted by human B lymphoblastoid cells (NC 37). May play a role in controlling immunoglobulin isotype selection as it also inhibits IgE synthesis (even in the presence of anti-IFN monoclonal antibody) and as a growth factor for activated CD4+ and CD8+ T-cells independently of interleukin-2, and for CD56+ NK cells but not resting peripheral blood mononuclear cells or resting or activated tonsillar B-cells. It is likely that interleukin 12 has a major role in protective immunity against viruses and is under study as an immunotherapy in HIV infection. Formerly referred to as cytotoxic lymphocyte maturation factor. Acronym: IL-12 (12 Dec 1998) |
| natural killer cells | Large granular lymphocytes which do not express markers of either T or B-cell lineage. These cells do possess Fc receptors for IgG and can kill target cells using antibody-dependent cell-mediated cytotoxicity. NK cells can also use perforin to kill cells in the absence of antibody. Killing may occur without previous sensitization. Synonym: NK cells. (05 Mar 2000) |
| killer cells, natural | Cells responsible for spontaneous cytotoxicity of a variety of tumour cells without prior immunization. These natural killer cells are found in non-immune humans and experimental animals and are thought by some to be the same as killer cells (killing by antibody-dependent cell cytotoxicity), but they can also kill in the absence of antibody. (12 Dec 1998) |

| killer cell | 1. <immunology> Mammalian cells which can lyse antibody coated target cells. They have a receptor for the Fc portion of IgG and are probably of the mononuclear phagocyte lineage, though some may be lymphocytes. Not to be confused with cytotoxic T-cells which recognise targets by other means and are clearly a sub set of T lymphocytes. This confusion exists in the early literature. 2. Natural killer cell are CD3 negative large granular lymphocytes, mediating cytolytic reactions that do not require expression of Class I or II major histocompatibility antigens on the target cell. 3. Lymphokine activated killer cells are NK cells activated by interleukin-2 (LAK cells). (13 Nov 1997) |

They capture, and swallow entire, large numbers of seals, porpoises, and dolphins, and are celebrated for their savage, combined attacks upon the right whales, which they are said to mutilate and kill. The common Atlantic species (Orca gladiator), is found both on the European and the American coast. Two species (Orca ater and O. Rectipinna) occur on the Pacific coast.

| natural killer cell |
A type of lymphocyte. Like cytotoxic T cells, NK cells attack and kill tumor cells and protect against a wide variety of infectious microbes. They are "natural" killers because they do not need additional stimulation or to recognize a specific antigen in order to attack and kill. Persons with immunodeficiencies such as those caused by HIV infection have a decrease in natural killer cell activity.
