Surprisingly, we found a negative correlation of CD300A‐CD330LF with T cell exclusion signatures, including myeloid‐derived suppressor cells (MDSCs), M2 subtype of tumor‐associated macrophages (TAMs), exclusion and TIDE score but a positive correlation with the T‐cell dysfunction score, IFNG, and merck18 signatures (Figure 8A). The gene discussed is CD300A; the disease is neoplasm.
