The first few months after infection with HIV (the human immunodeficiency virus).
During primary HIV infection, seroconversion occurs — the appearance of detectable antibodies to HIV in the blood. It normally takes several weeks to several months for antibodies to the virus to develop after HIV transmission. When antibodies to HIV appear in the blood, a person will test positive in the standard ELISA test for HIV.
Primary HIV infection may or may not include acute HIV, a flu-like syndrome that occurs immediately after a person contracts HIV. Acute HIV is characterized by fever, sore throat, headache, skin rash and swollen glands (lymphadenopathy).
- Primary dentition
The set of 20 first (deciduous) teeth. The primary dentition is as opposed to the secondary (permanent) dentition. At birth, both sets of dentition are evident by X-ray.
- Primary ciliary dyskinesia
The immotile cilia syndrome, a condition in which poorly functioning cilia (hairlike projections from cells) in the respiratory tract contribute to retention of secretions and recurrent infection. The condition is inherited as an autosomal recessive trait and is due to mutation in one of several different genes located on chromosomes 5, 9 and 19. About […]
- Proteolipid protein
PLP. Also called lipophilin. The most abundant protein of myelin, the covering and insulation around nerves. The gene PLP1 that codes for PLP is on the X chromosome. Mutations in PLP cause Pelizaeus-Merzbacher disease (PMD), an X-linked recessive disorder characterized by loss of myelin. PMD causes nystagmus (rhythmical oscillation of the eyeballs), psychomotor developmental delay, […]
The complete set of proteins expressed and modified following their expression by the genome. The term “proteome” was coined from the PROTEin complement of the genOME in 1994 by Marc Wilkins, a graduate student at Macquarie University in Australia. The analysis of the proteome is proteomics which Wilkins defined as “the study of proteins, how […]
