lecture 11 true and false quiz- immunology

Activation signals for T cells are transmitted through the BCR complex.

CD4 and CD8 are examples of coreceptors involved in T cell activation signals.

CD19 and CD21 are examples of coreceptors involved in B cell activation signals.

The signaling events initiated by BCR binding lead to T cell proliferation.

The maturation and activation of lymphocytes rely on the detection of non-specific signals through receptors.

Phosphorylation cascades, activation of transcription factors, and regulation of gene expression are involved in the immune response.

During T cell maturation, precursor cells migrate to the bone marrow.

B cell maturation involves interactions between developing B cells and stromal cells in the thymus microenvironment.

Maturation signals for T cells are mediated by interactions between thymocytes and stromal cells expressing bone marrow epithelial cell markers.

Lymphocyte activation is the process by which immature lymphocytes become functionally activated.

T cell activation involves recognition of lipopolysaccharide antigens presented by antigen-presenting cells.

BCR-initiated signaling pathways involve diverse B cell receptors recognizing a wide range of antigens.

NF-κB and AP-1 are transcription factors involved in the maturation of T cells.

The BCR-initiated signal pathway includes the activation of kinases and phosphorylation of ITIMs.

Lymphocyte maturation is the process by which mature lymphocytes develop into immature, non-functional cells.

Cytokines, cell surface receptors, and proteins involved in antibody production are not expressed in response to activated transcription factors.

Signaling pathways involved in the maturation and activation of lymphocytes respond to generic molecular cues.

Formation of the immune synapse involves the binding of antigens to T cells.
