Verified step by step guidance

Understand the role of B cells in the immune system: B cells are a type of white blood cell that play a crucial role in the adaptive immune response by producing antibodies.

Identify the different states of B cells: Naïve B cells, Activated B cells, Effector B cells, and Memory B cells.

Define a Naïve B cell: A Naïve B cell is one that has not yet encountered its specific antigen.

Define an Activated B cell: An Activated B cell is one that has encountered its specific antigen and has received the necessary signals to begin proliferation and differentiation.

Define an Effector B cell: An Effector B cell is a differentiated form of an Activated B cell that actively produces antibodies to combat the pathogen.
