The nerves are part of the Nervous System. The nerves will transmit the information that they get to the brain. Your brain will then send signals back to those nerve cells and tell them whether they should respond to the stimulus or whether they should just ignore.

Association
From the brain or nerve endings to dendrites
Sensory neurons are the type of nerve cells that carry messages from sensory receptors towards the brain to process and interpret information.
Neurons
Neurons or nerve cells are highly specialized and have the ability to transmit messages at a rapid rate. Neurons are the basic working units of the brain and they convey messages to other nerve cells, muscle cells or gland cells.

Assuming you mean "Nerve cells" when you say "brain cells", no. These cells are for sending and receiving messages and are not equipped with defence mechanisms.
The brain sends messages to the body systems through the nervous system. Nerve cells called neurons transmit electrical signals throughout the body, allowing for communication between the brain and different parts of the body. These signals help control movement, sensation, and various bodily functions.
nerves our individual cells-neurons
Nerve cells, or neurons, are specialized cells that carry messages through an electrical process in the brain. The brain contains about 100 billion neurons.
