โฆ Synopsis
Lymphocyte clones were isolated from CD4+ peripheralblood lymphocytes (PBL) of melanoma (Me) patient 9923 (HLA-DR7, DQw2, w6), co-cultured for 30 days with autologous accessory cells, allogeneic Me (Me 181 I) (HLA-DR7, DQwl, w2), IL-l p (2 U/ml) and IL-2 (15 IU/ml). The 55 clones tested displayed a CD3', CD4+, CD8-, T-cell receptor (TCR) cu/p+, y/8-phenotype. Twenty clones were assayed for proliferation in the presence of Me 181 I and B-lymphoblastoid cell line (LCL) 181 I, both expressing HLA-class4 and -11 (DR7 and DQw2 shared with patient 9923), intercellular adhesion molecule-I

Limiting numbers of peripheral-blood mononuclear cells (PBMC) from melanoma patients were stimulated with irradiated autologous tumor cells in the presence of interleukins-2 and -4 and in the absence of feeder cells. The responder cells were restimulated every week. After 2 to 4 weeks, the microcult
## Abstract CD4^+^ Th cells that are restricted by MHC class II molecules play an important role in the induction of antitumor immune responses. We have established a stable CD4^+^ Th cell clone (Th35โ1A) from the PBMCs of a patient with primary cutaneous melanoma. The Th cell clone is noncytolytic
