Aneuron and a white blood cell have very different functions. for example, a neuron can receive and respond to electrical signals while a white blood cell defends the body against infection. this is because

because some genes expressed in neuron is not expressed in WBC's.

Explanation:

Every cell in the body contains the same DNA sequence and the same gene but all the genes are not expressed in a cell. Each cell expresses a particular set of genes according to the function they perform.

For example, a red blood cell will express a gene that code for hemoglobin to carry oxygen but white blood cell do not carry oxygen, therefore, it will not express the gene of hemoglobin rather it will express a gene that make proteins that can be used to kill pathogens.

Therefore according to the function of cell genes are expressed so neurons express genes that make neurons receive and respond to electric signal.
