Receptor molecules
Hepatitis B (HBV) is a partial double stranded DNA virus (Hapadnavirus) that efficiently infects human liver cells, known as hepatocytes. The entry mechanism of HBV in to the human liver cells are yet to be elucidated deeply, but what known is the receptors candidate including the transferrin receptor, the asialoglycoprotien receptor molecule, and endonexin identified as the candidate receptors.The host cells for the hepatitis B are the liver cells called hepatocytes.
Vitamin B 12 is absorbed by cells in the upper part of the human small intestine, via receptor-mediated endocytosis.
Leydig cells are responsible for the production of testosterone in the testicles
HIV, the human immuno-deficiency virus, does not infect nerve cells, it infects white blood cells. (false)
The human eye contains specialized receptor cells that are responsible for night vision. These cells are referred to as rods.

Insulin is a hormone manufactured by B-cells in the Pancreas.

Proteins that act on your hormones.Hormonal proteins are proteins that can bind a hormone receptor on the cell and trigger a signal cascade to perform a cellular process such as proliferation, migration, metabolism, apoptosis and so on. Human growth factor, insulin, glucagan are few protein hormones.
Thymosin is a hormone produced by the thymus and it works with the lymph nodes and white blood cells, for example, to buildup immunity.SourceIntroduction to the Human Bodyby Gerard Tortora and Bryan Derrickson
This theory is false. Red blood cells do not contain a nucleus.

No they do not because diploid human cells have 46 chromosomes, Drosophila cells have 8 and giant sequoia tree cells have 22 (:
