A method for determining whether a subject is at risk for having a progressing or high-grade pre-invasive lesion, nodule or small mass, or having a solid malignant tumour is described the method comprising: (i) determining a ratio of activated and / or exhausted T cells:naive and / or resting T cells in a sample of blood obtained from the subject, wherein the determining comprises analysing T cells using cytometry to detect the presence or absence of a panel of biomarkers comprising Ki67 and CD39, or (ii) determining a ratio of activated and / or exhausted T cells:T cells which are not activated and / or exhausted T cells in a sample of blood obtained from the subject, wherein the determining comprises analysing T cells using cytometry to detect the presence or absence of a panel of biomarkers comprising Ki67 and CD39, (iii) determining a proportion of activated and / or exhausted T cells as a percentage of T cells in a sample of blood obtained from the subject, wherein the determining comprises analysing T cells using cytometry to detect the presence of a panel of biomarkers comprising Ki67 and CD39, and / or (iv) determining a proportion of activated and / or exhausted T cells as a percentage of T cells in a sample of blood obtained from the subject, wherein the T cells are CD4 T cells, and wherein the determining comprises analysing T cells using cytometry to detect the presence of a panel of biomarkers comprising FoxP3.

The present invention relates to a T cell receptor (TCR) specifically binding to KRAS_G12V mutant antigen, a fusion protein or a conjugate comprising the TCR, a nucleic acid encoding the TCR, and an engineered cell comprising the same, and a method for preparing the engineered cell. The present invention further relates to co-expressing an exogenous CD8 molecule and the TCR gene in T cells to enhance the function of T cells. The present invention provides use of the TCR and the genetically engineered cell in the detection, prevention and / or treatment of cancers related to the KRAS_G12V mutant antigen.

The present invention relates to viral vectors co-encoding an artificial CD4 T cell epitope (PADRE) for enhanced immune responses to encoded multimeric protein particle displayed vaccine antigens.
