Induction of lymphokine-activated killer activity in rat splenocyte cultures: The importance of 2-mercaptoethanol and indomethacin [PDF]
The role of 2-mercaptoethanol and indomethacin in the induction of lymphokine-activated killer (LAK) activity by interleukin-2 (IL-2) in rat splenocyte cultures was investigated.

Lymphokine-activated killer cells. Analysis of progenitors and effectors. [PDF]
IL-2 has been examined for its ability to regulate lymphokine-activated killer (LAK) activity. IL-2 is a potent activator of cytolytic activity against a wide array of tumor cells, including those from fresh autologous and allogeneic tumors. Using subpopulations of lymphoid cells that were separated on Percoll density gradients, and subsequently ...

Regulation of T cell lymphokine production by killer cell inhibitory receptor recognition of self HLA class I alleles. [PDF]
The killer cell inhibitory receptors (KIRs) are surface glycoproteins expressed by natural killer (NK) and T cells that specifically recognize defined groups of polymorphic human histocompatibility leukocyte antigen (HLA) class I molecules.

The Heterogeneity of Target Recognition by Lymphokine‐activated Killer Precursor Cells [PDF]
Lymphokine‐activated killer (LAK) cells were generated from peripheral blood lymphocytes (PBL) that were depleted of mature cytotoxic natural killer (NK) cells. PBL NK activity was abolished by pretreatment of effector cells with the toxic lysosomotropic agent l‐leucine methyl ester (LME) or by depletion of effector cells by K562 monolayer absorption ...

Experimental work has shown that during the development of tumours, host macrophages can deactivate natural killer cells and suppress lymphokine-activated killer cell development, apparently through prostaglandin E2 production.

The mechanisms by which polyamines accelerate tumor spread
Increased polyamine concentrations in the blood and urine of cancer patients reflect the enhanced levels of polyamine synthesis in cancer tissues arising from increased activity of enzymes responsible for polyamine synthesis. In addition to their de novo

Interleukin 2 activation of natural killer cells rapidly induces the expression and phosphorylation of the Leu-23 activation antigen. [PDF]
IL-2 potentiates both growth and cytotoxic function of T lymphocytes and NK cells. Resting peripheral blood NK cells can respond directly to rIL-2, without requirement for accessory cells or cofactors, and enhanced cytotoxicity can be measured within a ...

Interleukin-7 Induces Differential Lymphokine-Activated Killer Cell Activity Against Human Melanoma Cells, Keratinocytes, and Endothelial Cells [PDF]
To assess the potential role of interleukin (IL)-7 in immunotherapy of human malignant melanoma, we have examined the lymphokine-activated killer (LAK) cell sensitivity of four human melanoma cell lines against LAK cells generated by IL-7 or IL-2.

Biological processes and factors involved in soft and hard tissue healing
Abstract Wound healing is a complex and iterative process involving myriad cellular and biologic processes that are highly regulated to allow satisfactory repair and regeneration of damaged tissues. This review is intended to be an introductory chapter in a volume focusing on the use of platelet concentrates for tissue regeneration.

Natural killer (NK) and lymphokine-activated killer (LAK) cell functions from healthy dogs and 29 dogs with a variety of spontaneous neoplasms [PDF]
To investigate natural killer (NK) and lymphokine-activated killer (LAK) cell functions from 10 healthy dogs and 29 dogs with a variety of spontaneous neoplasms, large granular lymphocytes (LGLs) from blood samples were separated by a 58.5% Percoll ...
