Which cells recognize the antigens and assist in destroying them?

T-cells are a type of lymphocyte that play a central role in the immune response. They are specifically tasked with recognizing antigens, which are foreign substances that can provoke an immune reaction. When T-cells encounter an antigen, they bind to it through their receptors, which allows them to identify the invader. Once activated, T-cells can directly kill infected cells or help coordinate the immune response by signaling other immune cells.

In the context of the immune system, T-cells are crucial for identifying and targeting pathogens, including viruses and some bacteria, as well as cancerous cells. This ability to recognize and respond to antigens is fundamental for maintaining health and fighting off disease.

Other cell types mentioned in the options serve different functions. For instance, Merkel cells are involved in the sense of touch, melanocytes produce the pigment melanin for skin color, and desmosomes are cellular structures that help with adherence between cells but do not participate in immune responses. They do not play a role in antigen recognition or destruction, highlighting the essential and specialized function of T-cells in the immune system.
