Immunization of Alpacas (Lama pacos) with Protein Antigens and Production of Antigen-specific Single Domain Antibodies
Published on: January 26, 2019
Summary
Pioneering genetic research by Dr. Alison Goate identified the first mutation linked to inherited Alzheimer's disease (AD) and other neurodegenerative disorders. Her work continues to advance our understanding of dementia genetics.
Area of Science:
- Genetics
- Neuroscience
- Molecular Biology
Background:
- Alison M. Goate's research focuses on the genetic underpinnings of neurodegenerative diseases.
- Her early work identified the first mutation in the amyloid precursor protein (APP) gene associated with inherited early-onset Alzheimer's disease.
Discussion:
- Dr. Goate's laboratory has since identified mutations in additional genes contributing to Alzheimer's disease and frontotemporal dementia.
- Beyond dementia, her research also investigates the genetic basis of alcohol and nicotine dependence.
Key Insights:
- Discovery of the first gene mutation linked to inherited Alzheimer's disease (APP gene).
- Identification of multiple gene mutations responsible for Alzheimer's disease and frontotemporal dementia.
- Expansion of research into the genetics of substance dependence.
Outlook:
- Continued exploration of genetic factors in dementia and addiction.
- Potential for novel therapeutic targets based on genetic discoveries.
- Advancing personalized medicine approaches for neurological and psychiatric disorders.

Altruism
Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
Allosteric Proteins-ATCase
Binding sites linkages can regulate a protein's function. For example, enzyme activity is often regulated through a feedback mechanism where the end product of the biochemical process serves as an inhibitor.
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...

Cloning of Dolly the Sheep
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter telomeres than other...
Preparation of Alkynes: Alkylation Reaction
Introduction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.

Alkyl Halides
Structural Properties
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...

Alkali Metals
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).
