LTf

LTF is an acronym with several meanings across different fields. The most commonly cited is lactotransferrin, a glycoprotein found in milk and other mucosal secretions. Lactotransferrin is part of the transferrin family and binds iron, contributing to antimicrobial activity and modulation of the immune response. It is abundant in colostrum and milk, as well as in saliva, tears, and other secretions. Researchers study its roles in nutrition, host defense, and potential therapeutic applications.

In clinical research, LTF stands for Long-Term Follow-Up. This refers to the period after an initial study endpoint is reached, during which participants continue to be monitored to assess durability of effects, late adverse events, and long-term outcomes such as survival or disease progression. Long-term follow-up data help determine the enduring safety and effectiveness of interventions.

Other uses of the acronym exist but are less standardized and highly context-dependent. In some domains, LTF may denote organizations, technical terms, or project names specific to a field or region. Because meanings vary by discipline, readers should rely on contextual clues to identify the intended sense of LTF in a given article or document.
