BIO 110 Lecture Notes - Lecture 30: T Helper Cell, Reverse Transcriptase, Wolbachia
Document Summary
Wolbachia - a parasitic bacteria which can: Cause host speciation (creation of new species) Be used to stop the spread of zika and dengue fever. Allow host females to reproduce without males. Kill your dog! (with the help of a few worms) Adaptive immunity is specific - lymphocytes are crucial: Antibodies - proteins that bind specifically to substances identified by the immune system. Antigens - the portion of foreign molecules recognized and bound by antibodies. Both t cell receptors and antibodies bind to specific non-self molecules (antigens) During b cell development the gene segments are cut out and rearranged. One gene from each cluster is chosen randomly for joining, others are deleted a unique gene is created in each cell. Tip of antibody where it binds to the antigen is composed of six loops. Adjacent to six loops are beta strands holding the ends together.
