HLA (Human Leukocyte Antigen) class I antigens are crucial in the immune response to infections and also play a significant role in graft rejection. They present antigens to CD8+ T cells (cytotoxic T cells), which then target and destroy infected or foreign cells. While they do not directly activate B cells or CD4+ T cells, they are involved in the recognition of cells by the adaptive immune system and thus are important in the overall immune response.

Preeruptive caries refers to carious lesions that develop on teeth before they have erupted into the oral cavity. Research indicates that the mandibular second molars are particularly susceptible to preeruptive caries due to their position and the timing of their eruption. They are often more difficult to clean and can be affected by factors such as the presence of other teeth and the oral environment

Answer: 2) Increase in glucose transporters (GLUT4) on the cell membrane
Explanation: Insulin stimulates the translocation of glucose transporters (specifically GLUT4) from the intracellular vesicles to the cell membrane of muscle and adipose tissue cells. This increases the number of glucose transporters available for glucose uptake, thereby facilitating the influx of glucose into these cells.
