| ht | Abbreviation for height (and also heart). (12 Dec 1998) |

| ht29 cell | <cell culture> Human colonic adenocarcinoma cells that are able to express differentiation features characteristic of mature intestinal cells. These cells have mainly been used for studies related to glucose metabolism and hormone receptors. (12 Dec 1998) |
| HTLV | <virology> Type i: A human, single-stranded RNA retrovirus from the subfamily Oncovirinae which causes adult T-cell leukaemia and T-cell lymphoma and may also be involved in certain demyelinating diseases (diseases where the protective myelin sheath around nerve fibres are destroyed). HTLV-I is closely related to HTLV-II (60% of their genomes are identical). Type II: A human, single-stranded RNA retrovirus from the subfamily Oncovirinae which may cause diseases such as T-cell leukaemia and T-cell lymphoma (but this has not been proven). HTLV-II is closely related to HTLV I (60% of their genomes are identical). Type III: An obsolete term for human immunodeficiency virus (HIV), which causes Acquired Immunity Deficiency Syndrome (AIDS). Acronym: HTLV (09 Oct 1997) |
| HTLV-1 protease | <enzyme> Has been sequenced Registry number: EC 3.4.23.- Synonym: human t-cell leukaemia virus type 1 protease, pr14, HTLV-1 proteinase (26 Jun 1999) |
| HTLV-blv antibodies | Antibodies reactive with various types of human T-cell leukaemia/lymphoma antigens or bovine leukaemia virus antigens. (12 Dec 1998) |
| HTLV-blv antigens | Antigens associated with the HTLV-blv viruses. Htlv-I antigens and HTLV-II antigens belong to this group. (12 Dec 1998) |
| HTLV-blv infections | Infections caused by the HTLV or blv retroviruses. They include human T-cell leukaemia-lymphoma and adult T-cell leukaemia. (12 Dec 1998) |
| HTLV-blv viruses | Genus of the family retroviridae consisting of exogenous horizontally-transmitted viruses found in a few groups of mammals. Infections caused by these viruses include human b or adult T-cell leukaemia/lymphoma, and bovine leukaemia. (12 Dec 1998) |
| HTLV-I | <virology> A species of HTLV-blv viruses isolated from mature t4 cells in patients with t-lymphoproliferation malignancies. It causes adult T-cell leukaemia (atl), T-cell lymphoma, and is involved in mycosis fungoides, sezary syndrome and tropical spastic paraparesis. (12 Dec 1998) |
| HTLV-I antibodies | Antibodies reactive with the HTLV-I antigens. (12 Dec 1998) |
| HTLV-I antigens | Antigens associated with the HTLV-I virus. (12 Dec 1998) |
| HTLV-II | <virology> A species of HTLV-blv viruses that can transform normal T-lymphocytes and can replicate in both t- and B-cell lines. The virus is related to but distinct from HTLV-I. It is associated with T-cell hairy cell leukaemia, a relatively benign disease. (12 Dec 1998) |
| HTLV-II antibodies | Antibodies reactive with the HTLV-II antigens. (12 Dec 1998) |
| HTLV-II antigens | Antigens associated with the HTLV-II virus. (12 Dec 1998) |
| HTLV-III | <abbreviation> Human T-cell lymphotropic virus type III. See: human immunodeficiency virus. (05 Mar 2000) |
